Create Filled Contours script tool for ArcGIS 10


Contours are lines that connect locations of equal value in a raster dataset. They are useful because they can show the shape of the phenomena represented by the raster surface that may be otherwise difficult to see. In addition to … Continue reading

How large a DEM can the TopoToRaster tool create?

Thumbnail for the TopoToRaster output size blog

The TopoToRaster tool is primarily used to create hydrologically correct digital elevation models (DEMs) from contour data. Additional input information such as spot heights, known locations of sinks, streams and the outline of lakes can also be used to further … Continue reading

Automating geostatistical interpolation using template layers

Do you regularly perform geostatistical interpolation using the same parameters? We know that copying and pasting the same parameters over and over can introduce error and can be pretty tedious. However, this process can be streamlined using the Create Geostatistical Layer Tool.

Understanding Geostatistical Analyst Layers

The Geostatistical Analyst (GA for short) uses sample points taken at
different locations in a landscape and creates (interpolates) a continuous surface.
The sample points are measurements of some phenomenon, such as radiation leaking
from a nuclear power plant, an oil spill, or elevation heights. Geostatistical
Analyst derives a surface using the values from the measured locations to predict
values for each location in the landscape. Continue reading
