Map This! v0.4

[in7ane]

Deniska, I'll take a look at wrapping up the geo stuff over the weekend hopefully. Also, does this Canadian source look similar enough to the US data to be supported: http://www.geobase.ca/geobase/en/index.html (as for the UK, it seems in addition to paying for it in tax the data needs to be bough as well: http://www.ordnancesurvey.co.uk/oswebsite/ and I suspect it goes downhill from there for other countries).

Also found this for some more sample code: http://www.pagcgeo.org/

And some bug reports:

(1) Cursor note: Single cursor is included by default, rather than the once introduced double one.

(2) Distance calculation (marker + points, left top + right top keys) is wrong close to the equator (by a factor of 2 or so). I suspect you use the factor for the projection optimized (39.5?) latitude, an quick fix would be to calculate the factor on map load for the center of the map rather than the whole lat/lon to distance fix. Other distance and speed calculation also has this problem I guess.

(3) Time error, affects speed calculations? Seems to be 74 seconds/minutes rather than 60.

(4) GPS errors when maps contain -1 (or lower I guess) zoom levels.

This happens regardless of whether you are the -1 zoom level or at higher ones.


Cycles between data ok and showing arrow cursor

No data and showing out of range error

And no data without error and no arrow cursor


At all times, satellites, fix, and lat/lon headers display correctly.


Min zoom 0, showing that everything is in fact ok:

Min zoom -1, at zoom 0, the 3 states:

Min zoom -1, at zoom -1, has the ok state too:

The error seems to happen on navigating to the right location (in the screenshots I scrolled close to show that the map does contain it).

in7ane, welome back!

Don't bother with the US geocoder yet. I am changing the file format to allow reverse lookup too. I'll let you know when I am done - hopefully you'll be able to add it to the windows tool (or make a separate tool)...
The map data sources you listed seem to be in different from TIGER line data format.. so for now I'd like to stick to US only data...

I'll look at the alternative geocoder code, when I have time...

about the bugs:
1) - I liked the old cursor better so I left it..
I am actually considering major graphics gui redesign in the next release so cursors may change too...
2) For distance/bearing calculation I borrowed Rick Chapman's ( [email protected]) code.
I did not really checked the math behind it since it worked close enough for my few tests.
Perhaps you (or someone else with good knowlege of geometry) can take a look at the formulas and suggest a fix. All code is in NavigateCalculations.cpp::GeoRangeAndBearing()
3) I am aware of time display error. it should not affect speed/distance calculations though..

4) can you confirm that it does not happen on "positive zoom" maps?

Anyways, thanks for the detailed buglist and suggestions...
I am glad you are still onboard :-)

[in7ane]

Re 4) Yes, it only happens (at all zoom levels) if the map contains a negative zoom.

Except for the awkward wording above, this was to confirm that (min zoom is 0, with same area covered) - notice the zoom bar vs picture and others (I can get a video of the two cases if that helps - but should be easy to replicate):

I am changing the GUI a bit. It's still "work in progress"... The idea is to make it more skinnable..
Perhaps someone with more artistic talant could help me to design better panels and icons...
Here is some screenshots...

Hi Deniska.
Your V0.4 Map This is fantastic !
I recently used it over Christmas while driving over 2000 kms. Worked perfectly. Came in very handy. Only time it did not work was when the Holux GPS battery went flat !
One thing I do notice is that the overall trip distance counter resets to zero each time you re-start the app, or change maps. Would it be possible to have it save the last value, & keep adding to it, rather than resetting to zero each time. You could have a manual key press sequence to reset the trip distance when required.

My friend in Melbourne (Australia) was very impressed with your program, and he has not been a PSP fan ! He may buy one soon for this very purpose.

Cheers, Chris.

i had a question...now that 3.03 OE-A is out is map this compatible with this version?

i'm looking forward to usb/gps connection capability so that i can use either the sony gps or have easier connectivity with current gps antennas.

i would also like to see speech capability added in future versions.

i just recently upgraded my psp's firmware so i will be playing around with the software and order myself an antenna.

thank you for the awesome program...i will be recommending it to others.

It works...
I run it on two of my PSp's...

deniska, regarding 2) the distance calculations, sorry for the erroneous report - the problem was the map (the Google road/city coverage of Africa, although nice, is at best a guess of where things are it seems

And a real bug: if you scroll to an area of longitude <= -100 the battery % sign gets forced off the screen (if GPS is on part of the second field does instead).

This should not be a problem in the next release - since I am now displaying a battery icon instead of a number... Also, fixed the time display bug.. rearanged some controls, made the map cursor/map scroll faster, finished geo lookup and reverse lookup for US addresses...etc..
I'll post the newest beta version and the geotools probably tonight or tomorrow...

First off, I'd like to thank deniska, in7ane and all others who are developing this awesome tool for the psp. As a fan, and hopeful future user, I was wondering how long until the PSP GPS was ale to be implemented? maybe in the next month?, two months? I by no means am trying to be pushy, just incredibly eager to be able to use the tool myself. I already have the PSP GPS from Sony because I want to use it the day it becomes available. If there is anything that I or anyone else can do to assist let us know. I know there is a large group of people just waiting for the day the Sony GPS is supported. Thanks again for all of your guys hard work.
