GPSmapper - the easy and inexpensive GIS solution

• Load a list of geodic latitude and longitude points from a file and plot this as a map.
• Interface with GPSgrabber to download GPSdata from a Palm device.
• Display a scanned map image or aerial photograph in JPEG, GIF or bitmap format
• Calibrate map image by entering the logitude and latiude for any two points on the map
• Display geodic latitude and longitude for any point on the map as you move your cursor around.
• Calculate acreage simply by selecting the area on the map with your mouse.
• Calculate mileage by just clicking all along the road you wish to measure
• Calculate distance and heading between points on a map by simply clicking on both points
• Create text based vector files of any part of the map.
• Import text based vector files and display them on top of your map image.
• Handle geodic data in different formats like ddd.dddd, dd mm.mmmm or dd mm ss.ssss.
• Acreage can be shown as Acres, Hectare, Morgen, Sq Feet, Sq Yard, Sq Metre, Sq Mile or Sq Km
• Distances can in meters, feet, miles, nautical miles or kilometres
• Can convert GPSacreage PDB files into ascii text format. This means that you can also use GPSacreage a data collector.

Applications

• Precision agriculture
• Planning of hiking, cycling or off-road trips
• Locating Geocashes
• Estate agents can use it to plot the outline of a real estate on a map
• Amateur surveying tasks
• Creating maps of unchartered areas

Import and export ESRI Shapefiles

GPSmapper now also includes a free program called Mapper2Shape that allows you convert GPSmapper text files (CSV) to ESRI Shapefile format. It can also convert shapefiles into text file format that GPSmapper can import. The shapefile utility actually exports three files namely *.shp (shapefile itself), *.dbf (database file) and *.shx (index file). The reason for three files is to maintain compatibility with most GIS application that require all three these files before it can import a shapefile.

NavCalc - Navigational Calculator to do calculate distance and heading between waypoint. This application can also calculate the coordinates of a second or third point if certain parameters of the other two are already know.

GPScalc - GPScalc is a calculator to convert between geodic longitude and latitude to UTM eastings and northings and to calculate distance and headings between waypoints with great accuracy.

GPS Acreage - Use your Palm and a GPS to do surveying (calculate surface area for real estate of any shape of size). If you have a serial connection between your NMEA enabled GPS and your PDA, then it will automatically log readings from the GPS unit. Otherwise you can also manually enter the cooridinates of corner points.

GPSmapper - Use your Palm and a GPS to do draw detailed maps. GPSgrabber lets you collect GPS data on your PDA, and GPSmapper lets you display this data as a map on your PC.
