- Vector drawing utility for MAPPER-3a town plan tie-in. v1.7.
- ____________________________________________________________
-
- (Files produced work with MAPPER-3a v2.9 and above and MAPPER-3a/Ireland
- v1.2 and above)
-
- Please upload any and all town plans to the CIX 'mapper/townplans'
- conference/topic or e-mail them UUENCODEd to slitchfield@cix.compulink.co.uk
- or mail on Compuserve to 100640,107 or send on floppy disk to usual address!
-
- I can't offer any cash incentives for drawing and uploading *one or two*
- of your local towns in this way, but if you do more than ten, I'll think
- about it! Anyway, it's fun! 8-)) And think of the sheer usefulness if we can
- build up a library of 300 or 400 or more local town plans, all callable and
- displayable from MAPPER-3a!
-
- Installation
- ------------
- Then put VECTDRAW.OPO in a \OPO\ directory and run from there .....
-
- It needs two files from MAPPER-3a v2.9 or above (or MAPPER-3a/Ireland
- v1.2 or above) to run properly, I guess most people will have MAPPER-3a
- (or MAPPER-3a/Ireland) installed by the time they get to this stage, so
- there's no problem, but if you really do need to be picky, the GB.MP1
- and MAPPER.PIC (or IRELAND.MP1 and MAPPERIR.PIC) files need to be in a
- \APP\MAPPER3A\ (or \APP\MAPPERIR\) directory somewhere on one of the
- Psion's drives.
-
- Notes
- -----
- Operation should be obvious. Note that the naming convention for the town
- plan files is derived from the eastings/northings components of the town's
- position in the MAPPER-3a environment, with leading zeros if necessary) so
- as to keep the file name unique while conforming to the DOS 8.3 file name
- length convention.
-
- Note that if you want to do plans of overlay items (e.g.Gatwick Airfield),
- then there is a way, see appendix A for details.
-
- Note that VECTDRAW will only work with files in \APP\MAPPER3A\PLANS\ (or
- \APP\MAPPERIR\PLANS\ if you're using MAPPER-3a/Ireland) on your 'default'
- (i.e. RAM/writeable) drive.
-
- John Boyce's JBDATA utility makes a good tool for changing data once
- entered. If you have problems running JBDATA make sure a) you have enough
- memory free and b) you have the latest version. Please also remember to
- compress the file and delete the setup record before exiting.

- ----------
- Method for doing plans for overlay items (i.e. not towns)
- ---------------------------------------------------------
- (I've assumed you're using the GB product, but the principle is the same
- for the Irish one as well ....)
-
- a) Pick some place obscure in the GB.MP1 database, as our example, we'll
- use John O'Groats.
- b) Boot up VECTDRAW 1.7 and say you want to draw a plan of John O'Groats
- c) Draw the plan of your chosen place/item. For example, you might be
- doing a plan of Gatwick Airport. Do the plan with runways, terminals,
- roads, parking etc and then exit the program. VECTDRAW will tell you the
- file name it used for the plan, e.g. TP338973.MT1, which represents the
- coordinates of John O'Groats, which is what you asked for.
- d) Find out the eastings and northings coordinates of your item, e.g.
- Gatwick Airport (in the Airfields overlay) is 526 by 139. (Note that as an
- example, I've already done Gatwick Airport for you, included in the
- MAPPER-3a v2.9 ZIP set)
- e) In the \APP\MAPPER3A\PLANS\ directory on your default drive, rename
- TP338973.MT1 to TP526139.MT1 .
- f) That's it! When you now select Gatwick Airport (using Psion-Y etc), you
- can press the hot-key Psion-ENTER and get the airport's layout!
-
- (If all that sounds too confusing for you, then apologies. I will try and
- make things easier in a future release)
