It’s been a while since I’ve posted and things have been busy. Soccer season has ended, the kids have finished school and I’ve finished up at my client site and moved back to the office. Among the many things I’ve been working on, I’ve started building an open-source GIS stack. It’s not entirely open-source since…
Creating ArcObjects Spatial Reference Objects From PostGIS Spatial Reference Definitions
As discussed in my previous post, I’m trying to beef up the spatial reference support in zigGIS. I am doing this mainly to introduce support for user-defined spatial references. It pretty much boils down to querying the the appropriate SR from the PostGIS spatial_ref_sys table and applying the value of the srtext column to create…
zigGIS and Spatial References, Part 3
This post updates this post and this one. One of our beloved 5 users ;-), James, pointed out recently that zigGIS still has issues with user-defined coordinate systems. Alas, this is true. When we implemented support for on-the-fly “reprojection,” we limited it to the standard EPSG SRIDs supported by both PostGIS and ArcGIS. This was…
Moving Forward On A Couple of Fronts
Well, it’s been a while since I’ve posted anything technical. Work has been a little crazy and I’m not willing to carve into time with the family to keep other stuff moving. As a result a few things have been sitting for a while but I’ve been able to get around to two things. First,…
Today We Are All Hokies…
Hokie Nation has invited everyone to wear their school colors today as a show of solidarity. I will. You should, too. I work with a lot of VT grads. I have seen that their lifelong identification with VT rivals that of Notre Dame alumni. So, from this Retreiver to all of Hokie Nation: My prayers…
Sometimes It’s the Simple Stuff…
I’ve become very enamoured of the new VE-based map display at weather.com. For example, here’s my location. My wife had to drive out to Ohio yesterday and, with the big storm moving across the country, I’ve been spending more time at weather.com than usual. Anyway, one of the most useful features of the display, from…
Outta Here…
I’m off with the family for a week of sun, sand and frothy umbrella drinks. I’ve spent the last couple of days working on a WCF web service wrapping some PostGIS calls. I hope to be able to write about it not long after I get back. I’m also continuing with the ArcCatalog objects for…
zigGIS 1.2 Is Out
Congratulations to Paolo for getting zigGIS 1.2 out the door. He’s put a lot of work into fixing problems with selections and renderers and making it a much more usable tool. His post contains a list of features implemented at this version and it’s really a huge step forward. I am focusing on developing catalog…
PostGIS and ArcGIS 9.2
Updating my earlier post: I completed my upgrade to 9.2 yesterday with the installation of the last service pack. The first thing I did was upgrade zigGIS to ensure that there wouldn’t be problems. I have to say that the first thing I noticed was all of the tools ESRI has integrated with VS2005. I…
Almost There with 9.2
Okay, I have no one to blame but myself. I have Desktop and the full EDN kit (except for ArcIMS) installed. Therefore, I’ve uninistalled everything 9.1 and reinstalled everything 9.2 and now I get to do the service packs. One day, I’ll get back to coding, I’m sure. Meanwhile, the front of my forehead keeps…
