Posted by Pano Voudouris in ArcGIS on April 7, 2013
For those of you who never heard Qt, its s a cross-platform application framework used to develop GUI applications software, and its what is used for all the QGIS forms. And now ESRI announced the beta release of the ArcGIS Runtime SDK for Qt. From the release announcement: ArcGIS Runtime SDK for Qt is designed to help C++ developers use […]
How to make your first QGIS custom form on Windows
Posted by Pano Voudouris in Open Source GIS, Python, QGIS on March 17, 2013
For a long time I wanted to give a go at creating a QGIS plugin. Nothing in particular, just a ‘Hello World’ plugin or similar so I could understand how the whole QGIS/python thing hangs together. Seasoned readers of my blog may have noticed by now that I mainly (only?) work on Windows OS. And […]
Are we smarter because of Google? Gimme a break
Posted by Pano Voudouris in Google Maps on January 6, 2013
To forewarn you- this is a rant. But I have to blow some steam here- just can’t easily accept pompous, big-headed statements like this one: Effectively, people are about 20 IQ points smarter now because of Google Search and Maps. They don’t give Google credit for it, which is fine; they think they’re smarter, because […]
Displaying WMS Legends in Silverlight with a WCF Service
Posted by Pano Voudouris in ArcGIS, ESRI, Silverlight, Web Mapping on January 4, 2013
This may be re-inventing the wheel big time, but whilst working on an ArcGIS Silverlight app making heavy use of WMS Layers, I could not, for the life of me, find a way to display the WMS legend in the ‘standard’ legend control. Now, there may be a version of API I missed, or plain […]
Identify Task for WMS layers in ArcGIS Silverlight
Posted by Pano Voudouris in ArcGIS, ESRI, Silverlight on November 17, 2012
Apparently it doesn’t seem to be working as expected- even if the WMS layer is stored in an MXD document. Instead of returning the layer attributes, it returns the WMS GetFeatureInfo request i.e. something similar to: http://www2.demis.nl/WMS/wms.ashx?WMS=SAMPLE&VERSION=1.3.0&REQUEST=GetFeatureInfo&< >CRS=CRS:84&BBOX=-180,-90,180,90&WIDTH=1304&HEIGHT=652&LAYERS=Countries& QUERY_LAYERS=Countries& STYLES=&EXCEPTIONS=XML&FORMAT=image/png&INFO_FORMAT=text/html&FEATURE_COUNT=50&I=304&J=192 The workaround is to use this URL to make a direct call to the WMS […]
Batch Geocoding with Google Maps
Posted by Pano Voudouris in Google Maps on October 31, 2012
Yes, another one of those. Last week I had to geocode a bunch of addresses which were held in a csv file and came across this really handy geocoding utility/page, (which you can download it on your PC) written by Esa. As expected, it takes a list of addresses and geocodes them. Geocoded addresses and coordinates are […]
CitizensOnDuty.com: Reporting neighborhood problems with a twist
Posted by Pano Voudouris in Ελληνικά, online maps, Web Mapping on October 7, 2012
It seems that Greece has just acquired its own flavour of crowdsourced, problem reporting app. Citizensonduty.com is what you would expect from the likes of FixMyStreet and SeeClickFix: On top of a Google map background, users can report problems in their local area so that the Local Council will (in theory) fix them. Citizens on […]
