New Map Warper

I’d like to announce the release of the new Map Warper. It’s an online map rectifier, based on Rails, and using GDAL, OpenLayers, with OpenStreetMap in mind.

It has some new bells and whistles you may like.

  • Search for maps.
  • Users & “MyMaps”.
  • Image cropping.
  • Calculation of RMS errors.
  • Export in different formats.
  • Activity feeds.

I’ve imported all the previous maps so if you used the previous app on wrp.geothings.net, don’t worry, your maps and WMS will still work. If you want to work on them some more, then you may need to warp them again.

You don’t have to make an account to use it, but if you do, you get to track your maps, activities and shortly, be able to make your maps “private”.

Couple of caveats, it will resize oversize images (over 1500×1500)  to make processing quicker and as before, it’s beta so there may be a few kinks but they should be ironed out quickly, so please tell me of them, ta.

It is still open source and is available at:  http://svn2.geothings.net/mapwarper/ or a slightly older snapshot on github if you would like to grab a copy.

First peek into the map warper project

Pre-pre-alpha and so likely to change from day to day, or break, here’s the project I started a while ago and have been working on getting usable, but you should be able to have a play on this sneak peek at least. It’s an open source map georectifier / warper, written in Ruby-on-Rails and using GDAL, Mapserver, and OpenLayers, and it’s provisionally called “Map Warper”. It can be found here: http://wrp.geothings.net

Inspired by Metacarta’s Map Rectifier, which I have written about here and here, it was originally primarily planned to be able to support the WMS plugin I developed for the JOSM editor, and also to assist OpenStreetMap surveyors who collect and want to use their own ground control points. (The other driving force was the desire for me to use some fine out of copyright maps and make a free geodataset of Roman Britain, and historical features in general)

It will have additional features in the near future, such as enabling TileCache for WMS-C/TMS, export to Google style tiles, GeoRSS and KML, amongst other things. As mentioned above, it is still unstable and in active development, so things will change and your data probably will be deleted!

We’re looking for a nice name for it, and a nice logo would be good too!
