ArcGIS Python Reproject Geometry Object List

ArcGIS Python Reproject Geometry Object List

Frequently I have a large list of geometry objects I need to get reprojected for analysis. A while back I discovered the reprojectAs method of the arcpy.Geometry [http://desktop.arcgis.com/en/arcmap/latest/analyze/arcpy-classes/geometry.htm] object. While useful, I still needed a way to handle a

Grocery Home Delivery with ArcGIS

Grocery Home Delivery with ArcGIS

Most of the time my work related blog posts are much more on the side of technical and less on the side of marketing. This particular post likely ebbs more toward the latter than the former. However, this story map does an excellent job of communicating how to get from

Use Symbology from Point Feature Layer in Leaflet

For simple web mapping, recently I have been experimenting with Leaflet [http://leafletjs.com/] and Esri-Leaflet [http://esri.github.io/esri-leaflet/] quite a bit. For simple and quick mapping, Leaflet using Esri-Leaflet to support Esri published services is a very viable solution. One difficulty I initially struggled with is getting

Yeoman Generator for Bootstrap-Map-JS

Getting started building web mapping applications can be a daunting task at best. In many cases, the recent emergence of generators has greatly lowered the point of entry when getting started with many web frameworks and API's. Unfortunately, when I first started working with the Bootstrap-Map-JS project templates, there was

Esri Southeast User Conference - Python Presentations

07 May 2014 Update: The code created in both presentations has been included in the embedded referenced GISTs. This coming week the annual Esri Southeast User Conference (SEUC) is being held at the Charlotte Convention Center in (no kidding) Charlotte, NC. I will be presenting two presentations on Python. Since

Cleanse Feature Class Names in Python

Today I ran across a problem with what should be a simple solution, but took me the better part of the morning to figure out...primarily because I was not familiar enough with regular expression matching. ArcGIS is pretty picky about feature class names, whether a feature class in a

Retrieving Esri Class Certificates

Not too long ago Esri transitioned to delivering class completion certificates electronically. This makes it a little easier to avoid misplacing them, making copies and retrieving them if lost. If you have attended an Esri class, you can find your certificate by pointing your web browser of choice to the

Set Up PyScripter to Create ArcGIS Python Toolboxes

For the last year or so, my Python IDE of choice has been PyScripter. Recently I have started to create ArcGIS Python Toolboxes. PyScripter is still my editor of choice for this task...with a bit of customization. This requires two steps, adding the unique file extension (pyt) to the

ArcGIS API for JavaScript Resource Page

Sometimes I work with it more and sometimes less. For the last few months I have been focusing on other things. As a result, I have not been paying as much attention to the updates to the Esri web API's. This morning though, I went to see about finding a

Esri on GitHub

There are quite a few code samples available from Esri, but they are somewhat scattered around the Esri Resource Center. Now Esri is starting to share many of these resources on GitHub where you can access these resources. If you are familiar with any of the ArcGIS for specific industry

Publish a Cached Map to ArcGIS.com Without Burning Credits

Publishing a map to ArcGIS.com, typically it is preferable to cache the map for faster rendering and performance. However, the larger the spatial extent, the more credits will be used to create the cache. Recently a solution to this has been created. ArcGIS.com can now publish tile packages

Create Enterprise Geodatabase from XML Workspace document

Note: I have updated this toolbox to include more functionality, ported it to a Python Toolbox, and created a GitHub repository [https://github.com/knu2xs/sde-workspace-creation-toolbox] for it. Teaching classes frequently necessitates quickly creating and setting up enterprise geodatabases using ArcGIS SDE technology. To make my life easier, I keep

Iranian Ballistic Missile Range

[http://res.cloudinary.com/joelmccune-com/image/upload/v1408384262/iranBallisticMissile_lowRes_ogmdbu.png] Being a GIS geek, when reading the New York Times and The Economist on my iPad, current events in the Middle East always get me to thinking about how the geography all fits together. During the last few

Esri Disaster Response

[http://www.esri.com/services/disaster-response/index.html]Today I received an email highlighting the assistance Esri is standing by ready to offer for those assisting with disaster response. This email included a link directly to the Esri Disaster Response Webpage [http://www.esri.com/services/disaster-response/index.html]. Types

Lat/Long Table to Feature Class using Modelbuilder

Going from a flat table with latitude and longitude to a point feature class in ArcGIS Desktop using ModelBuilder can, at first, be a somewhat daunting task. My first attempt at this took most of a morning. Accomplishing this requires using theMake XY Event Layer and Copy Features Tool together

Simple Test Box Setup for Esri's Silverlight Viewer

The new Esri Silverlight Viewer has recently been released for for public beta. This locally hosted Silverlight web application is by far the quickest and easiest method to create a very professional web mapping application. Testing this new technology does not require administrative access to an installation of ArcGIS Server.
