WhiteBox GAT – Geospatial Analysis Toolbox (Review)
Whitebox GAT (Geospatial Analysis Toolbox) specializes in terrain analysis. But you can do processes like LiDAR and hydrology analysis.
Azimuthal Projection: Orthographic, Stereographic and Gnomonic
The azimuthal projection plots the surface of Earth using a flat plane. For example, common azimuthal projections are gnomonic, stereographic & orthographic
Equal Area Projection Maps in Cartography
The equal area projection retains the relative size of area throughout a map. So that means at any given region, it keeps the true size and area of features.
What is an Aspect Map?
In the mountains, the terrain slopes are in all directions – east, west, north and south-facing. The compass direction that the slope faces is slope aspect.
How To Vectorize Images with ArcScan
You can take any image, and you can vectorize it with ArcScan. This means you’ll spend less time digitizing and more time doing other important things.
Inverse Distance Weighting (IDW) Interpolation
Inverse Distance Weighting (IDW) interpolation estimates unknown values with specifying search distance, closest points, power setting & barriers.
How Universal Transverse Mercator (UTM) Works
Universal Transverse Mercator (UTM) segments the Earth into 60 zones (each UTM zone is 6°) and projects each zone with an upright cylinder of its own.
Location-Allocation in ArcGIS (Site Selection)
Tech-savvy companies are using the location-allocation tool to find optimal location and target market. Here’s an ArcGIS solution to locate your company.
What Is a Map Legend?
A map legend is used to define features in a map. Point, line and polygon symbols in a legend key is the driving-force to understand what is found in a map.
