From the looks of it, you are getting a python error because the headers argument is expecting a dictionary, not a string The following works for me on the entire date range: import requests url = "http://www.ncdc.noaa.gov/cdo-web/api/v2/data?datasetid=GHCNDMS&locationid=ZIP:28801&startdate=2000-01-01&enddate=2010-01-01" # replace 'myToken' ...

Here is the code that could be used. The code is base on the reading of a s57 map . QList<QgsSymbolV2*> lSymbols = lrenderer->symbols(); QList<QgsSymbolV2*> lSymbolsToRender = lrenderer->symbols(); QStringList lListValue; lListValue << "0" << "3" << "5" << "10" << "15" << "20" ...

You probably do not want different symbol layers (they will be painted on top of each other). You probably want to look into QgsCategorizedSymbolRendererV2 which lets you define multiple categories with a different symbol for each. setDataDefinedProperty is for defining a style property based on a feature attribute like the color defined by a field with ...

@Cameron Sloan Number 3 will be difficult for any application to accomplish because this is a data problem. Google has access to volumes of Digital Globe imagery (among other sources) which allows for historic imagery comparisons. ESRI and other vendors do not have access to such data similiar to the scale of Google.

ArcGIS is coming out with ArcGIS Earth in December. They are announcing it this week and I am sure that the beta will be out soon. Since ArcGIS API supports all that you listed (even 3D in the 4.0 Beta API) there shouldn't be any of the criteria mentioned that ArcGIS Earth won't cover. I will update this answer when I get more information.

Kiks73, I've been using TerraExplorer by Skyline Software Systems (http://skylinesoft.com/skylineglobe/corporate/products/terraexplorer.aspx?) for years at my client site and TE is the closest application I've seen as a one-to-one replacement for GE. TE can handle your list of items (except for #3) out of the box and TE's API is also open. Let me know if ...

Make sure you get the identifier correct: mQgsCoordinate->createFromOgcWmsCrs("CRS:83"); You get a return value directly from the createFromOgcWmsCrs method which indicates if the call was ok. To make your development easier: it's straightforward to use the python console for finding the correct usage: >>> a = QgsCoordinateReferenceSystem() ...

I found this post after a search for a comparison of current web mapping toolkits. I think it is still mostly relevant. However, I wanted to share OSGeo's comprehensive list of toolkits as an additional resource.

At least two OSM aware programs that I know are based on Qt framework: Merkaartor and Marble, both are opensource. And OSM frameworks based on C++ are listed in the OSM wiki at http://wiki.openstreetmap.org/wiki/Frameworks

This question had the second rank on Google when I searched for OpenLayers versus Leaflet so I thought I'd mention that there is a basic tutorial that compares the APIs of both OpenLayers 3 and Leaflet by having you build the same thing in both of them. It is written by Astun Technology and the tutorial tasks are: Basic map with OSM tiles OS-GB Map with ...

If you are looking for a service, there is PickPoint. It engages nominatim and OSM for geocoding.

You can try PickPoint. That's a pretty expeditious service providing geocoding as well as reverse geocoding by attractive price. You can even choose Free plan if the number of requests is below 2500 per day.

In your parent class you have some virtual functions and it is an abstract class (so you can't create objects from that class). So you have to implement them in your child class. Here you have a nice explanation of virtual functions.
