= Specification =

There are two basic areas covered by following technical specification:

 * MOSS4G Framework - foundation [wiki:Libraries libraries] available for Windows CE applications development
 * [wiki:Specification/MOSSMAP MOSSMAP] - main end-user application based on the MOSS4G Framework dedicated for Windows Mobile 5.0+ for Pocket PC and Smartphone

== General Features ==

 * [http://moss4g.telascience.org/ MOSS4G] is based on [http://opensource.org Open Source Software / Free Software]
 * Target platform
   * [http://en.wikipedia.org/wiki/Windows_CE Windows CE 5.0] and higher (Windows Mobile 5.0+ for Pocket PC and Smartphone)
   * in future, it should be possible to support other mobile platforms like Linux or Symbian, on volunteer basis
 * Standard PDA Hardware as of 2007
 * Internet connection: GPRS IP connection (not always online) or 3G IP connection (ie. CDMA2000 Verizon 3G, mostly online)
 * I18N support
 * OGC protocols support: WMS, WFS, WPS
 * Vector and raster formats support using [http://www.gdal.org/ GDAL] library
 * GPS support for navigation and vector editing

== MOSSMAP Application Features ==

=== Map Management ===

 * Load map from project file
 * Save map to project file
 * Import/Export map from MapServer file
 * Publish map to remote Web server
 * Upload complete map to remove server
   {{{
A project includes the shapefile with the digitized polygones, the corresponding cache and one or more simple files (like PDF).
The uploading process has to use authentication.
A simple web form could be used to do the uploading (perhaps package all files in a specfic way into one .zip file and
upload this single file - the server will know that to do with it)
   }}}
 * Consideration of on-fly projection of layers added to a map
   * Selection of map projection (default: projection of a first layer)
   * Projection definition for each layer
   * Consideration of projection defined for GeoTiff? or Shapefile (.prj file)

=== Layer Management ===

 * Add/Remove layer
 * Toggle layer visibility in current view
 * Reorder layers

==== Vector layer ====

 * Layer style customization
 * Features classification based on value of selected attribute using:
   * Single symbol
   * Graduated symbol
   * Continuous symbol
   * Unique symbol

 * Formats:
   * ESRI Shapefile
   * WFS

==== Raster layer ====

 * Data formats:
   * GeoTIFF
     * single (Just one tiff for one layer)
     * tiled (many images form a single layer ... shape file indexing or tile cache)
   * WMS

 * Cache tool:
   {{{
Tool to cache a area to be specified on a WMS layer (x meters around a point) onto local storage so that it creates and stores a "map" file as well.
Use WMS and WFS request to download bitmaps and vector data (stored as Shapefile) - names etc. are to be hardcoded.
It must be possible to give each of these caches a name. It will represent a directory.
Option to delete caches (dialog with a list, you can pick one or many and press a "remove" button.
   }}}
 
=== Navigation ===

 * Zoom-in
 * Zoom-out
 * Zoom to extent of all layers
 * Zoom to extent of selected layer
 * Pan
 * Query vector feature (display attributes)
 * Measurement tools: distance, area
 * Scale: 
   * as a scale bar
   * in textual form

==== Routing ====

 * Using OGC WPS protocol implemented with PyWPS Route Path
 * LOS calculations

=== Features Editing ===

 * Add/Remove point
 * Add/Remove line
 * Add/Remove polygon
 * Add/Move/Remove vertices
   * Capture coordinates from GPS
 * Edit attributes
 * Save digitized feature

=== [wiki:GPS] Support ===

 * Show current GPS position
   * graphical cursor in map window
   * latitude/longitude/altitude in textual form
 * Show GPS diagnostics details
 * Capture and store GPS track to a file
 * Waypoints management support
   * Retrieve and display waypoints from GPS unit
   * Store waypoints in a file
   * Send waypoints through WFS-T
 * Import/Export GPX
