If you’ve read most of my previous posts, you know I’m a big fan of all things python in GIS. Specifically relating to ArcGIS, because well…that’s the software with which I’m most comfortable/proficient. Like many GIS professionals, my education and experience has revolved around ESRI products. I am however aware of, and have used, other platforms like QGIS, PostGIS, MapBox, Manifold, etc., but just do so much less frequently. Read More »

I like to think that I learn more every day, but I still really embrace being a computer novice in a lot of ways. About four years ago, I learned about using Windows’ Task Scheduler to run processes on a defined timetable. The typical things it became useful for in my daily activities were: backing up data from my local machine to a server, running processes during off-hours that consume significant system resources, and automating web download workflows/preparing the data before I arrived at work. It’s best for uses requiring no user input, since the user is often absent during a scheduled task run. Read More »
Web-based mapping application, with a built in case management system. Agents create and maintain new cases along side historical ones and the system geographically references large amounts of data and integrate external data sources in order to identify crime patterns.
Working together with the National Protection and Programs Directorate (NPPD) and the Office of Cyber and Infrastructure Analysis (OCIA), we provide geospatial visualization of critical infrastructure, along with threats, to protect against, respond to, and recover from threats and hazards.
Managing a team of Geospatial Analysts, and all their ongoing projects, requires a decent bit of effort for the Project Manager on one of our current contracts. At the onset, the PM would ask each GA what they were working on, obtain it verbally or via email, and manually enter the information into an excel spreadsheet. He would then discuss the spreadsheet with the client each week, noting any task updates or closures. The importance of the spreadsheet and the weekly client meetings cannot be understated; however, I believed that the amount of labor associated with tracking tasks could be greatly reduced.
While working with geospatial information, it is often advantageous to find out how close one particular piece of data is to other pieces of data. This leads to a greater understanding of the area of study. The knowledge of how things relate to one another spatially is articulated in Waldo Tobler’s First Law of Geography. It states that “everything is related to everything else, but near things are more related than distant things.” Read More »
Over the past decade, GIS professionals who can manipulate the software both manually and automatically are becoming increasingly more marketable within the industry. Automating mundane/repetitive tasks frees up time to focus on more advanced analyses and other GIS processes.
On one of our current contracts, we are required to create map products in response to “breaking news” events. These maps provide situational awareness to our client regarding the status of assets within their area of jurisdiction. Time is of the essence during these events, and the faster a map product can go out, the better.
