Scaled Maps

[klaus]

Here is an application for displaying scaled maps.

The project began already in this thread http://www.basic4ppc.com/forum/chit-...html#post20687 , but ceasar and myself find that it's right place is here.

What can be done:
- Different maps can be loaded.
- The maps can be scaled, and the scaling saved (two points only yet).
- Drawings can be made onto the maps on 3 different layers:
- polylines with different colors, line widths
- circles with radius in meters, different colors, line widths, filled or empty
- texts with different colors, font sizes, font styles, with or without background color
- bitmaps, with or without background color, 4 bitmaps are predefined, these can be deleted and others loaded.
- Select any element of the drawing and modify, or delete it. To change the position of an element, click on it, move it and release, or change the coordinates.
- New points can be added to polylines.
- Save and load drawings. The saved data is just the geometry of the drawing elements, with a reference to the map. To load drawings, the program shows only those belonging to the map.
- Calculate the length of a polyline
- 2 maps of Cape Town are included, one with a km scaling and the other one with long, lat in degrees, sources Google Maps and Google Earth.

What can not be done yet:
- Scaling with 3 points
- Undo and redo

What is still missing:
- no GPS support

The help file is here.
www.basic4ppc.com/files/ScaledMapHelpE.zip
It contains the help file itself and the map I used to create this help file.

I would be pleased to have some feedback of what is missing, improvement suggestions and bug reports.

Best regards.

EDIT: 2009.11.21
Version 2.0 bug renoval and some minor changes.

EDIT: 2011.02.27
Version 3.0 with a beginning of GPS support not really tested.
Leave it as it is.

Hi Klaus

Thanks for your effort and input. To be honest with you, I did not get a chance to play with it yet. I am trying very hard to get the Surveying program that I had running on the Workabout (from Psion) to run on a Windows Mobile device. I am nearly finished, but there are still some hicups that I need to sort out. Every surveyor that is using the old program is breathing down my neck to test out the new program.

At the moment I am sitting here with 7 different surveying instruments that I need to interface and the approach is a bit different than in "OPL" or NSBasic.
(I wasted my time with NSBasic!)

This should take about another week, then I will work through your Mapping program and give you some feedback.

Klaus, once again I say thank you very much for your help.

Regards
Michael

Hi Michael,

Don't worry, I saw with your other posts that you were quite busy with other problems. I did interface measurement instruments and a computer with serial port years ago in VB, but don't remember all details.

There is now a help file in the first post.

Best regards.

It's an amazing program, but there's a bug in it: If you zoom in to the maximun, scroll to the right-bottom corner, and then zoom out, there is a strech of the image. Then, when zooming in, an error ocurred in line 578 in module Map.bas.

Hi Ariel,
Thank you for the bug report.

A new version is updated in the first post with some minor changes.
The help has also been updated.

Best regards.

Hi Klaus

it would be very cool to get the Scaling3points and GPS support in Version Scaled Map 2.0 to work. that would really be great, and a killer source, to learn from!

Best regards

Hi William,

I don't plan it in a short time.
If there is any interest from other users I could consider it.
Probably not the GPS support because I am writing another GPS program.

But feel free to take it and add your own code.

Best regards.

I understand.

Hi Klaus

I have been looking at your program scaled map with the idea of adding the gps part to it.

Did you ever work out the code for converting a lat/long coord set to your program's map-scale coordinate?

If I could convert a lat / long (or utm) coordinate set to your scaled map coordinate system I could add the gps functionality.

Hi Sarah Ward

Thats sounds fantastic!

PS. i am able to set a pizel on the Map, and thats all yet. Ha, ha.

I am a bit slow with Variables and constants, and a few other.

Best regards

William
