Peter:
We are all beginning to hear ESRI beat its drum about the "latest enhancement"
of ArcView to be roled out as "ArcGIS 8.1". From a presentation I
heard yesterday, I am more convinced than ever that Maptitude still represents
superior value as a desktop GIS. While I'm not tempted at all by
ESRI's "siren song", it might be useful for existing Maptitude customers
to get a comparative chart of the expected functional capability of MT
4.5 vs. ArcGIS 8.1...for example, ArcGIS 8.1 apparently will finally be
offering import/export of multiple (up to 40?) geographic formats...a feature
of Maptitude for a number of years (but a format for format comparison
would be useful). We keep getting from you these "snippet" insights
to the improved features of the 4.5 product (and I know you don't want
to promise something that you might not be able to deliver), but it would
be nice to know what the whole package will offer and how "backward" compatible
it will be (e.g. old add-ins which worked with 3.0 were rendered
useless with the migration to MT 4.0). Also, how soon before it is
expected to complete beta testing and move into production?

XY space, which can be longitude/latitude. Objects are exactly that:
points, lines, polygons, rectangles, even round-cornered rectangles! No
topological relationships to worry about.Maptitude is a geographic environment, where everything is stored in
longitude/latitude and projected for display. Map features are points (no
topology possible), lines and their endpoints (every line begins and ends
at an endpoint, and has 0+ shape points), or areas (stored as edges with
left/right area IDs, and with any number of holes and islands). While
copying and pasting are not impossible, topology takes some effort to maintain.We have add new capabilities to Standard TransCAD for editing lines,
including copying and pasting segments and conflating segments (getting the
better coordinates from one layer into another), and Maptitude 4.5 will get
some of TransCAD 4.0's capabilities, such as:- Rubbersheeting
- Clip by Area
- Merge GeographyThis list is a good place to discuss new capabilities, and we will listen.
