Cartographica 1.4.2 is now available, and it's got a little bit of everything to it: new features, performance enhancements, and bug fixes.
This release ended up taking a bit longer than we expected as we have been working hard to fix the bugs reported in 1.4 and 1.4.1. But, we haven't just been working on fixing bugs, we've also been enhancing the capabilities and performance of the existing capabilities of Cartographica, with improvements in everything from WFS compatibility to execution speed and progress information for many of our analysis tools.
I won't take up the space here to enumerate all of the changes, as they are covered almost exhaustively in the release notes, however I will point out a few of the areas we have been working on.
Analysis Tools
We introduced a lot of new tools in version 1.4, and we have been making improvements to the performance and interface for these. In particular, almost all of the analysis tools provide more progress information now and may be canceled. For those who work in more than one window at a time, Cartographica no longer makes you wait in all windows while analysis is performed for one window. This means you can continue to work on another map while performing more complex analysis on a map in the background. All search and overlay operations are substantially improved and we are continuing to follow additional optimization paths (while maintaining accuracy).
Geocoding
Because of the Bing geocoder service that we also support, many folks don't use the built-in geocoder. However, for tasks involving historical data, or large amounts of data being processed in a small area, it's often a faster mechanism (and it doesn't require a network connection). In this release, we've significantly improved the handling of whitespace, negative address ranges in the streets files, additional abbreviations, and support for streets whose names begin with "Ste".
File Import/Export
Most of the changes to file import involved upgrading to the most recent libraries for external file formats, such as MrSID®. These should improve compatibility and performance.
For export, we've fixed a bug involving line style export to Illustrator and enhanced the Save window to include file extensions that appropriately default for the selected file type.
ESRI File GeoDatabase can now receive the entire map instead of being broken into a set of GDB files per layer.
Live Maps
The big change for live maps is that Custom OSM layers can now point at basically any tile source that uses a similar format to OpenStreetMap but isn't actually an OpenStreetMap server. For those of you with access to tiled services from an ESRI ArcServer map, this means that you can access those tiles from Cartographica as well. For an OpenStreetMap server, you can just use the URL of the service in the box. For other services, you'll need to use a more complete URL with {zoom}, {x}, and {y}, representing the zoom level, x tile id, and y tile id. Here are some examples:
For ESRI ArcServer maps, end the URL with {zoom}/{y}/{x}, so if the base URL of the map is
http://myserver/ArcGIS/rest/services/MyMapLayerName/MapServer
the URL you would use is:
http://myserver/ArcGIS/rest/services/MyMapLayerName/MapServer/tile/{zoom}/{y}/{x}
For Google-style maps, the URL is more complicated, so if the base URL of the map is
https://mymapserver.com/foo/x=9&y=23&z=6&scale=2&s=Ga
the URL you would use is:
https://mymapserver.com/foo/x={x}&y={y}&z={zoom}&scale=2&s=Ga
At the moment, all of the key services are using the same CRS, which is the Web Pseudo-Mercator and thus Cartographica will automatically determine the right information and display it correctly.
WFS Layers
We continue our improvement of support for WFS layers. This release includes better handling of WFS 2.0.0 servers (such as most recent versions of GeoServer) as well as backwards compatibility with older 1.1 and 1.0 services. We also fixed a bug in handling single polygon layers in GMLv3 layers (multi-polygon layers were fine).
The Web Feature Layer Attributes window (available from Layer > Web Feature Layer Attributes... and when you add a new web feature layer using File > Add Web Feature Layer...) has been enhanced to allow limiting of requests to the server (necessary for some servers that don't know their own limitations) and the introduction of manual filters. We hope to make filters easier in future versions, but for now if you know the XML filter language (or can have somebody work up a filter for you), then you can paste that directly into the Filter box and it will be applied to layer requests.
The Future
We have many plans going forward, including improvements to our existing features and additional features for analysis, presentation and exploration. We sincerely appreciate your support.
