Mapwel contains special tool for easy download of large freeware mapsets from internet and their conversion to routable format. This tool allows to define mapset parameters and create map tiles automatically. Each map in the set is trimmed and aligned with other maps for seamless navigation from one map to another. Imported map files in both raster and vector format (especially *.shp files) may use various projections and geographic systems. Mapwel supports hundreds of the commonly used systems, including UTM (Universal Transverse Mercator). Internal format of map data in Mapwel is WGS84, because this format is also internal format of the GPS units. Although user can select various coordinate systems in GPS, coordinates are always calculated from WGS84 format. Therefore, Mapwel converts all input data into WGS84. If you need to get raster image into GPS with just a few mouse clicks, this is the right tool for you. Mapwel provides automatic ‘one-click’ vectorization of raster images (satellite imagery or scanned maps). Most of Garmin units do not allow to load raster image directly into the GPS and use it as a map. Therefore, this function automatically vectorizes raster image and creates vector file compatible with GPS. Mapwel provides calibration tool to establish relation between raster image and map coordinate system. Result is a map with Lat/Lon grid parallel to the screen edges and coordinates assigned to left, right, top and bottom edge of the map. GPS units use basic (pre-defined) and user-defined sets of polygon patterns, line styles and symbol icons. Mapwel provides easy-to-use editor of user styles, which are supported by most of the new Garmin GPS. This is another tool for faster vectorization of the raster image. It allows to vectorize one object (or set of similar objects) at a time, but it cannot vectorize whole map with different types of objects at once. Tracing should be repeated for respective types of objects (filled areas, roads, rivers, etc.). Trace tool works on images with any common color depth (including True Color and bi-tone) that are sufficiently clean. Object Inspector box at right side of the main Mapwel window displays information about respective map objects and simplifies the object manipulations. It also allows to select one or several objects in the work space. Each map object has adjustable properties like name, comment (text that is displayed in GPS when cursor stays on top of the object), type, max. zoom level, etc. POI (points of interest) may have address and phone number assigned. It is also possible to define properties of the whole map, like name, copyright text, address format, internal map ID, map draw priority and zoom levels of map layers. Finished map can be saved into Mapwel *.mpw file format, exported into *.img, *.kml or other supported format , or uploaded directly into the GPS. Export of map into other than *.mpw file is supported by Mapwel Advanced version only. Mapwel includes separate MapUpload program for loading *.img files into the GPS. MapUpload also allows to pack several img files into a single executable file to distribute to your friends or customers. Source.
