This utility will generate special TYP file, which can be used for identification of element types used in map.
With older (not NT) maps, identification was easy. You could just open map in gpsMapEdit and look at "Map properties / Statistics" page. Or you could look directly into map, and element types were immediately visible, so you knew that river is for example type=0x42.
New (NT) maps have different structure (GMP), and gpsMapEdit cannot open them. And because there is so much new element types (starting from 0x100), it is really hard to tell what type and subtype was used for different elements.
So here comes this utility. It creates special TYP file for given map, and this TYP file contains definition for all possible types and subtypes. When used in MapSource, map looks really strange. But each element has now different color, and color value is derived from element's type and subtype.
With this special TYP file you can use some free screen-pixel-reader (for example Pixie), point mouse on questionable polygon, line, or POI and look at it's color value.
When you are finished with all major polygons (basemap area, cities background, etc.), enter their types and subtypes into "exclude" fields above, and generate new TYP. This will usually reveal some polygons which were previously hidden by larger ones (for example, when city area was drawn over parks and playgrounds, etc.). You can then repeat these steps again and again ...
Polygon types are represented as HTML #values, eg.:
- #RRGGBB means #_TTTSS, where TTT is type and SS is subtype. First character is generated randomly for better color differences and should be ignored.
- For example:
#E04B00 means type=0x04B, subtype=0x00
#310218 means type=0x102, subtype=0x18
Line and POI types are represented as HEX 0xvalues and have reverse order, eg.:
- 0xBBGGRR means 0x_TTTSS, where TTT is type and SS is subtype. First character is generated randomly for better color differences and should be ignored.
- For example:
0x200600 means type=0x006, subtype=0x00
0x310218 means type=0x102, subtype=0x18
Don't forget, that 0xBBGGRR is NOT the same as #RRGGBB, because 0xHEX and #html values have different order of R, G and B values.
So always read polygon values from #html field, and line/POI values from 0xHexadecimal field of "Pixie" utility.
Hope this helps.
