GIS Tools for Hadoop
On Sunday, David Kaiser and his Big Data crew released the GIS Tools for Hadoop Project on GitHub.
The project contains an open source framework and API that enables big data developers to author custom spatial applications for Hadoop. Continue reading
Python scripting with 64-bit processing
Last week 64-bit Background Geoprocessing was made available for download. We’ve had a few questions from keen Python scripters who want to “get out of the application” and use their big data crunching scripts in 64-bit. If you’re one of those keen scripters, all you need to do is make sure you’re executing against 64-bit Python; no other special commands or tricks needed. Continue reading
The new ScratchGDB and ScratchFolder environments
One of the enhancements to the 10.1 release was the addition of two new environment variables (scratchFolder and scratchGDB) as mentioned in the What’s New for Geoprocessing in 10.1. (If you haven’t read it, check out all enhancements!). While new … Continue reading
Path Slope tools are available for download
The new Path Slope tools are available for download from Arcgis.com. The Path Slope toolbox is an Esri Defense toolbox for planning. The zip file contains the tools, supporting layers for output symbology, a sample geodatabase with a roads feature … Continue reading

Field mapping and Python scripting
A number of geoprocessing tools including Spatial Join (Analysis), Append (Management), Merge (Management), Feature Class To Feature Class (Conversion), and Table To Table (Conversion), have a parameter for controlling how fields from the input dataset(s) are processed and written, or … Continue reading
Using spatial analysis to measure city accessibility by intersection density
Past work has shown the more accessible an urban area, the more walking and public transit use is promoted, whilst car journeys and traffic speeds are reduced. What makes an area accessible and how do we determine if an area … Continue reading
Create isogonic lines using the Make Isogonic Lines Model
Isogonic lines, or lines of equal magnetic declination, are useful as supplementary cartographic data on navigational charts. Prior to ArcGIS 10.1, a geoprocessing tool called Magnetic Isolines, available with Esri Production Mapping, was used to create isomagnetic lines based on … Continue reading
Drop All Representations Tool
Representations allow you to build complex symbols and add dynamic effects to meet your organization’s cartographic specifications. During the process of building these you may end up creating multiple representations. By using the recently released Drop All Representations tool you … Continue reading
Obstruction Analysis using Solar Radiation Graphics
This blog describes the use of Geoprocessing tools including the Solar Radiation Graphics tool in the Spatial Analyst extension for evaluating poor performing weather stations that both, recorded and, were powered by solar radiation. Overview In order to stimulate economic … Continue reading
