Live Parking Capacity With Leaflet

First things first: you will notice I’ve added comments to my blog. This is new. I realize that I am now opening the floodgates to the internet, so it will be an interesting experiment. I will not hesitate to remove comments again if it gets out of hand.Here’s a quick and fun one. If you’re […]

Talking Oblique System Camera Calibration at IGTF 2016

I’ll be in Fort Worth, TX for the 2016 American Society for Photogrammetry and Remote Sensing’s annual conference, the Imaging & Geospatial Technology Forum (IGTF). I’ll be presenting a paper I’m co-author on: A Study on Oblique Camera Systems and the Stability of their Parameters. In it, we look at the methodology used to calculate […]

3D Visualization of the Grand Canyon with Potree

Last fall, Keystone Aerial Surveys flew a test flight over a branch of the Grand Canyon with their Ultracam Falcon Prime digital camera. I had the opportunity to play with the data a bit in post processing. I balanced the imagery, did the aerial triangulation and bundle adjustment on the block, and computed a 3D […]

DIY GeoTech: GeoDuino Part 1

DIY GeoTech? “Geospatial” doesn’t live in a vacuum. It’s not exclusively maps and geo data and GIS, as some analysts wish. The entire study of geography has been revamped and invigorated by the leaps-and-bounds advances in geospatial hardware technology. I’m going to call it GeoTech, but don’t think I like fun buzzwords. I know, “blah […]

Talking Remote Sensing + 3D Prining at the 2015 ESRI UC

I’ll be giving at talk at the 2015 ESRI International User Conference as part of the 3D GIS Forum. It’s kind of a funny topic. We use imagery to derive 3D Models all the time. This particular talk will cover a case study of how we modeled, build and printed a full color, to-scale model […]

Histogram Stretch and You: a PSA on ArcMap Defaults

Below is an important public service announcement for all people using ArcGIS to view image files. This is probably the single most common question I get when I deliver imagery to clients.Have you ever been working with imagery in ArcMap and the colors just don’t match across image files? Have you ever spent a lot […]

Web mapping for fun and zero profit

Update again, 5/6/2016: I was looking over this again and realized two major things have happened that affect the content of this post. 1) Leaflet has changed so now it’s much easier to load external GeoJSON without using jQuery and 2) I’ve gotten a whole hell of a lot better at Javascript. I admit it […]
