Spatial Data Mining I: Essentials of Cluster Analysis
Whenever we look at a map, it is natural for us to organize, group, differentiate, and cluster what we see to help us make better sense of it. This session will explore the powerful Spatial Statistics techniques designed to do just that: Hot Spot Analysis and Cluster and Outlier Analysis. We will demonstrate how these techniques work and how they can be used to identify significant patterns in our data. We will explore the different questions that each tool can answer, best practices for running the tools, and strategies for interpreting and sharing results. This comprehensive introduction to cluster analysis will prepare you with the knowledge necessary to turn your spatial data into useful information for better decision making.

Introduction to Spatial Analysis (GIS) using ArcGIS Desktop and the Time Slider Window
www.knowgis.com (13.2 Minutes) Visit www.KnowGIS.com for more free tutorials. In this free tutorial, we animate spatial features over time, using the ArcGIS Time Slider Window. During this tutorial, we use ArcGIS Destop 10, talk of Spatial Analysis as a method of analysing data though a process of applying analytical techniques. provides an example of how it could be used to facilitate visual analysis. As part of this tutorial, we will "time-enable" spatial data relating to water wells mapped for the state of Montana, USA. We will visualize how data changes over time which provides opportunities for in-depth visual analysis. After a short discussion on Spatial Analysis, we will set the foundation for using the Time Slider Window so we can view temporal change though an animation. The animation will then be exported to a movie for use in non-linear video editing. The Time Slider window provides unique controls that allow spatial data to be visualized in an "animated map". The Time Slider window is invoked by clicking the Open Time Slider Window button on the Tools toolbar. Keep in mind that this button may be unavailable if you do not have any time-enabled datasets in your map, scene, or ArcGIS globe. We;ll add a temporal dataset to ArcMap and then set its time properties in order to visualize it through time using the Time Slider in ArcMap, ArcGlobe, or ArcScene. Visit www.knowgis.com for more tutorials or to learn more about the complete training series for learning and knowing ArcGIS Desktop. Thank you.

ArcGIS Geostatistical Analysis: Spatial Interpolation (IDW)
Spatial Analysis means to manipulate geographic data to extract new meaningful information. Interpolation is one of such geostatistical methods in which we use known values at sampled points to generate a continuous surface giving us prediction of values at unknown points. IDW is an interpolation technique in which values of cells are predicted by averaging known point values while processing each neighborhood cell. Points which are closer to the estimated cell have more weightage in the averages. IDW is preferred over Kriging in situations when sampled points are densely distributed over the surface. How to perform Spatial Interpolation in ArcGIS: 1. Open ArcGIS. 2. Add XY data in ArcMap. In this case, we have an Excel spreadsheet of Monthly Average Precipitation Data in .XLS format. 3. Convert XY data to Shapefile (.shp format). 4. Add boundary over data. 5. Select points which lie within the boundary. 6. Export selected points to new Shapefile. 7. Search for the IDW tool within the Interpolation toolset inside Spatial Analyst toolbox. 8. Choose the column of known point values as Z value field. 9. Mask the output of Raster Analysis to the given boundary in the Environments Settings. The Interpolated surface is obtained which can also be exported as a Raster Dataset for further analysis.

Scales of Measurement - Nominal, Ordinal, Interval, Ratio (Part 1) - Introductory Statistics
This video reviews the scales of measurement covered in introductory statistics: nominal, ordinal, interval, and ratio (Part 1 of 2). Scales of Measurement Nominal, Ordinal, Interval, Ratio YouTube Channel: https://www.youtube.com/user/statisticsinstructor Subscribe today! Lifetime access to SPSS videos: http://tinyurl.com/m2532td Video Transcript: In this video we'll take a look at what are known as the scales of measurement. OK first of all measurement can be defined as the process of applying numbers to objects according to a set of rules. So when we measure something we apply numbers or we give numbers to something and this something is just generically an object or objects so we're assigning numbers to some thing or things and when we do that we follow some sort of rules. Now in terms of introductory statistics textbooks there are four scales of measurement nominal, ordinal, interval, and ratio. We'll take a look at each of these in turn and take a look at some examples as well, as the examples really help to differentiate between these four scales. First we'll take a look at nominal. Now in a nominal scale of measurement we assign numbers to objects where the different numbers indicate different objects. The numbers have no real meaning other than differentiating between objects. So as an example a very common variable in statistical analyses is gender where in this example all males get a 1 and all females get a 2. Now the reason why this is nominal is because we could have just as easily assigned females a 1 and males a 2 or we could have assigned females 500 and males 650. It doesn't matter what number we come up with as long as all males get the same number, 1 in this example, and all females get the same number, 2. It doesn't mean that because females have a higher number that they're better than males or males are worse than females or vice versa or anything like that. All it does is it differentiates between our two groups. And that's a classic nominal example. Another one is baseball uniform numbers. Now the number that a player has on their uniform in baseball it provides no insight into the player's position or anything like that it just simply differentiates between players. So if someone has the number 23 on their back and someone has the number 25 it doesn't mean that the person who has 25 is better, has a higher average, hits more home runs, or anything like that it just means they're not the same playeras number 23. So in this example its nominal once again because the number just simply differentiates between objects. Now just as a side note in all sports it's not the same like in football for example different sequences of numbers typically go towards different positions. Like linebackers will have numbers that are different than quarterbacks and so forth but that's not the case in baseball. So in baseball whatever the number is it provides typically no insight into what position he plays. OK next we have ordinal and for ordinal we assign numbers to objects just like nominal but here the numbers also have meaningful order. So for example the place someone finishes in a race first, second, third, and so on. If we know the place that they finished we know how they did relative to others. So for example the first place person did better than second, second did better than third, and so on of course right that's obvious but that number that they're assigned one, two, or three indicates how they finished in a race so it indicates order and same thing with the place finished in an election first, second, third, fourth we know exactly how they did in relation to the others the person who finished in third place did better than someone who finished in fifth let's say if there are that many people, first did better than third and so on. So the number for ordinal once again indicates placement or order so we can rank people with ordinal data. OK next we have interval. In interval numbers have order just like ordinal so you can see here how these scales of measurement build on one another but in addition to ordinal, interval also has equal intervals between adjacent categories and I'll show you what I mean here with an example. So if we take temperature in degrees Fahrenheit the difference between 78 degrees and 79 degrees or that one degree difference is the same as the difference between 45 degrees and 46 degrees. One degree difference once again. So anywhere along that scale up and down the Fahrenheit scale that one degree difference means the same thing all up and down that scale. OK so if we take eight degrees versus nine degrees the difference there is one degree once again. That's a classic interval scale right there with those differences are meaningful and we'll contrast this with ordinal in just a few moments but finally before we do let's take a look at ratio.

Digital Mapping, GIS, Remote Sensing
Land use planning and resource management today requires that a vast amount of geographic intelligence is readily available in a timely fashion. It requires accurate, scalable information that can be used for strategic planning over very large land bases as well as detailed high resolution for operational on-the-ground applications. In the past this range of uses has been largely unattainable without completing multiple level inventories at high cost. Fortunately things have changed. With high speed computers, powerful software and high resolution digital imagery and lidar, the world and its resources can now be mapped at very high resolution and scaled at what ever level of detail is required for a specific application. Furthermore, the data can be mined and retrospective analysis performed at virtually any time new questions arise. Silvatech has been applying digital mapping, GIS. and remote sensing analysis technology since 1986. Since then we have been researching and developing a multitude of applications for geomatics technology in land and resource management. Our mapping division, Earth Imaging Technologies Inc., together with our imaging partners, offers a wide variety of digital imagery and lidar data sets and derived map products. We host several industry-standard digital mapping and remote sensing platforms, as well as proprietary in-house software. Silvatech can work with both hard copy prints and diaps as well as full digital imagery and lidar. We work closely with subject matter experts to ensure that our mapping solutions reflect the best knowledge base available and make sense on the ground. We help you get the most from your data. Often government agencies, industrial resource developers and other land and resource managers possess very valuable digital data that they are not getting full value from. Silvatch has decades of experience in mining digital land and resource data sets and extracting valuable information that can save signinficant time and costs.  We also have found that some clients, unkowingly, have data sets that are inaccesable, incompatible, incomplete, inconsistant or non-conforming to standards.  Silvatech can help you audit, organize, warehouse, serve and improve the integrity of your data so that it can support your application needs much better. We have the tools and experience to empower you with enabling land and resource intelligence.

SUBSCRIBE to our Google Earth flights channel - https://www.youtube.com/channel/UC6UuCPh7GrXznZi0Hz2YQnQ Geospatial analysis, or just spatial analysis, is an approach to applying statistical analysis and other analytic techniques to data which has a geographical or spatial aspect. Such analysis would typically employ software capable of rendering maps processing spatial data, and applying analytical methods to terrestrial or geographic datasets, including the use of geographic information systems and geomatics. Geographic information systems (GIS), which is a large domain that provides a variety of capabilities designed to capture, store, manipulate, analyze, manage, and present all types of geographical data, and utilizes geospatial analysis in a variety of contexts, operations and applications. Geospatial analysis, using GIS, was developed for problems in the environmental and life sciences, in particular ecology, geology and epidemiology. It has extended to almost all industries including defense, intelligence, utilities, Natural Resources (i.e. Oil and Gas, Forestry ... etc.), social sciences, medicine and Public Safety (i.e. emergency management and criminology), disaster risk reduction and management (DRRM), and climate change adaptation (CCA). Spatial statistics typically result primarily from observation rather than experimentation. Vector-based GIS is typically related to operations such as map overlay (combining two or more maps or map layers according to predefined rules), simple buffering (identifying regions of a map within a specified distance of one or more features, such as towns, roads or rivers) and similar basic operations. This reflects (and is reflected in) the use of the term spatial analysis within the Open Geospatial Consortium (OGC) “simple feature specifications”. For raster-based GIS, widely used in the environmental sciences and remote sensing, this typically means a range of actions applied to the grid cells of one or more maps (or images) often involving filtering and/or algebraic operations (map algebra). These techniques involve processing one or more raster layers according to simple rules resulting in a new map layer, for example replacing each cell value with some combination of its neighbours’ values, or computing the sum or difference of specific attribute values for each grid cell in two matching raster datasets. Descriptive statistics, such as cell counts, means, variances, maxima, minima, cumulative values, frequencies and a number of other measures and distance computations are also often included in this generic term spatial analysis. Spatial analysis includes a large variety of statistical techniques (descriptive, exploratory, and explanatory statistics) that apply to data that vary spatially and which can vary over time. Some more advanced statistical techniques include Getis-ord Gi* or Anselin Local Moran's I which are used to determine clustering patterns of spatially referenced data. Geospatial analysis goes beyond 2D and 3D mapping operations and spatial statistics. It includes: Surface analysis —in particular analysing the properties of physical surfaces, such as gradient, aspect and visibility, and analysing surface-like data “fields”; Network analysis — examining the properties of natural and man-made networks in order to understand the behaviour of flows within and around such networks; and locational analysis. GIS-based network analysis may be used to address a wide range of practical problems such as route selection and facility location (core topics in the field of operations research, and problems involving flows such as those found in hydrology and transportation research. In many instances location problems relate to networks and as such are addressed with tools designed for this purpose, but in others existing networks may have little or no relevance or may be impractical to incorporate within the modeling process....
