In+ersec+ion for Spatial People

Via this Google story I learned about MapKnitter, an open source tool to upload your own aerial imagery and combine it into a GeoTiff and TMS/OpenLayers map. MapKnitter is aimed at images coming from balloons and kites.

From their wiki: "MapKnitter (MapKnitter.org) is a free and open source tool for combining and positioning images (often from MapMill.org) in geographic space into a composite image map. Known as “orthorectification” or “georectification” to geographers, this step covers the process of figuring out where images can be placed on an existing map, and how they can be combined, or “stitched” together. You are likely to have many images of overlapping or identical areas, which is why MapMill or some type of sorting is used to determine which source images to use from the original set."

MapKnitter uses GDAL, Leaflet, OpenLayers, Prototype, Ruby on Rails and other open source software.

DM yesterday published an article named Ten Things You Need to Know About OpenStreetMap. While you probably already know all this if you're a regular reader, it still constitutes an excellent refresher.

Follow the provided link for the details, here's the ten items:

1. OpenStreetMap's definition; "OpenStreetMap is a free worldwide map, created by people like you."
2. OSM’s Name is Singular
3. The OpenStreetMap Foundation Manages and Supports the Effort
4. OSM is Changing its License from Creative Commons to ODbL
5. Mapping Parties are Events to Expand OSM
6. Google’s Recent Decision to Charge Heavy Users of its Google Maps API is Pushing Developers to OSM
7. Where to Get OSM Tiles
8. Many Apps Offer OSM Data as an Option
9. Some Countries are Heavier OSM Contributors and Users than Others
10. OSM has an Annual Conference, The State of the Map

Also announced earlier this week is the opening of the registration for State of the Map 2012 conference, to be held in Tokyo September 6-8th, just before FOSS4G 2012 at the same location. [correction: rather same "region" of the world... FOSS4G 2012 being held in Beijing, sorry]

While we did mention Leaflet a few times in the past months, it never had it's own entry on Slashgeo, until today! Leaflet is a modern, lightweight open source JavaScript library for Interactive maps by CloudMade.

Its description: "Weighing just about 22kb of gzipped JS code, it still has all the features most developers ever need for online maps, while providing a fast, pleasant user experience. It is built from the ground up to work efficiently and smoothly on both desktop and mobile platforms like iOS and Android, taking advantage of HTML5 and CSS3 on modern browsers. The focus is on usability, performance, small size, A-grade browser support, convention over configuration and an easy-to-use API. The OOP-based code of the library is designed to be modular, extensible and very easy to understand."

MyGeoCloud.com is a new OpenSoure project and a web service. It offers geospatial storage, WMS and WFS-T services for accessing data and transactions. Besides that it offers a built-in web mapping client and online editing of data. But MyGeoCloud is also a platform on which you can build your own location based web applications using a JavaScript API.

The core component of MyGeoCloud is the PostGIS database software, which is used for storage and geospatial operations. MapServer is used for map rendering and for tile caching TileCache is used. OpenLayers is used for the web map clients. The WFS-T service is implemented in the code base.

The goal is a all-in-one solution for storage, geospatial operations, geospatial web services and web mapping.

Frisco, TX – ThinkGeo has released version 5.5 of Map Suite, its full line of GIS software components for .NET developers.  This major milestone refresh introduces two important new features: a robust map printing and page layout system, and support for generating visually stunning contour lines (also known as isolines).  A wide variety of bug fixes and stability improvements round out the 5.5 release of Map Suite.

With Map Suite’s new printing system, .NET software developers can use the Map Suite GIS controls and components to add robust map printing capabilities to their GIS applications.  Map Suite 5.5’s new PrinterLayer can programmatically prepare and print attractive page layouts containing not only high-resolution maps, but also images, labels and titles, scale bars and lines, north arrows and data grids.  In addition, Map Suite Desktop and WPF Desktop Editions have the added bonus of the PrinterInteractiveOverlay, which allows the end user to assemble their own custom page layout using a graphical user interface.  Either way, the end product can either be printed, exported to a PDF document or a raster image file.

Contour lines (also known as isolines) are also new to Map Suite 5.5 and offer a compelling way to visualize breaks between different groups of data – such as elevation levels, soil properties and much more.  All editions of Map Suite now have the ability to generate contour line maps either dynamically or via a set of input data.

Both the new printing and contour line features are supplemented with sample code available on the ThinkGeo Wiki (http://wiki.thinkgeo.com) and 30-minute instructional videos narrated by David Rehagen, Map Suite’s Chief Architect.

Other noteworthy enhancements in the Map Suite 5.5 release include a high-performance rewrite of the Bing™ Maps overlay (which also now includes support for Bing Maps Enterprise Keys), the ability to download tiles from a WMS layer simultaneously instead of serially in Map Suite Web Edition, an update to the latest address data in Map Suite Geocoder, and an overhauled routing API for improved performance in the Map Suite Routing Extension.  Beyond that, a variety of bug fixes and stability improvements have been added throughout the Map Suite GIS product range.  Complete change logs are available at the ThinkGeo Wiki (http://wiki.thinkgeo.com), the company’s official online source for Map Suite documentation, reference and learning material.  The 5.5 update includes new builds of all of Map Suite’s major editions, including Desktop, Web, Silverlight, WPF Desktop, Services and WMS Server Editions, as well as the Map Suite Geocoder, World Map Kit and other Map Suite extensions.

ThinkGeo has also announced plans to release special “daily builds” of each Map Suite product in the coming weeks, which will introduce several new features that did not make it into the final Map Suite 5.5 release.  Developers will be able to test these new capabilities, which include memory usage and drawing speed improvements, support for the latest versions of MrSid and ECW files, and XML serialization for storing layers, styles and much more across different Map Suite versions.

ThinkGeo’s biannual release plan puts them on track to unveil the next major milestone of Map Suite, version 6.0, in May of 2012.  GIS professionals who wish to request specific features or enhancements for the next revision of Map Suite are encouraged to visit ThinkGeo’s Enhancement Tracker at http://helpdesk.thinkgeo.com/EnhancementTracker, where they can vote on their favorite enhancement ideas and suggest new ones directly to Map Suite’s development team.

MapQuest introduced MapQuest Vibe in beta: "Today, we’re launching MapQuest Vibe, which is your shortcut to becoming a local, anywhere.  This early beta cuts through the clutter of ratings, lists and pins on a map, by giving you actual rankings of places based on key criteria within a local neighborhood context. [...] The “local knowledge” is generated with a new patented algorithm called VibeRank.  This blended social-algorithmic formula takes several implicit signals (like searches on MapQuest and cartographic data), creates a baseline ranking and then layers on explicit social signals from the new Vibe pages. Based on this algorithm, MapQuest Vibe profiles more than 50,000 neighborhoods, 27,000 cities and 50,000 hotspots in the U.S., reaching 98 percent of the population."

MapQuest Vibe presents neighborhoods from a different angle than other mapping sites and it's integrated with Facebook. Directions Mag offers a round up of early MapQuest Vibe reviews. In other recent MapQuest news, they now have a map widget for GoDaddy-hosted websites.
