For the Spline with Barriers interpolation tool, the enhancements that were made when the tool was implemented in ArcGIS Pro 2.0 are now also available in ArcGIS 10.6. Let’s have a look at the history of this tool, and some … Continue reading
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
Introduction Sampling design is a critical part of any study involving modeling and estimation based on data that is sampled from natural resources or other phenomena occurring in the landscape. Statistical considerations related to sampling are part of a larger … Continue reading
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
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.
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
