Map Coordinates

[ukenuke]

Nevermind my question. I found that it was just a rounding error I was doing! After I fixed it, I had no more problems.

I added some features to rowcolcal.xls

1. Takes Worldwind clipboard contents as input
2. Added USGS levels

I used this spreadsheet to indentify dds files that had errors when downloaded.
I'd zoom in on the area
copy its coordiantes into excel
delete the file in explorer
zoom out World wind then back in - fixed.

Hi!
I'm new here. But I hope, I can do my part.
I improved the excel-program of "dsten" a little bit.

[attachmentid=255]

At first (because I'm from Germany) I had little problems with calculating because the "." and "," - sings. Therefore I programmed a little workaraound.

Furthermore I wrote (in VBA - so activate the macros) a tool to identify the .dds-files without the corresponding .tif-Files. So you can list or delete all the damaged files in all folders you want. Because this was a problem of an other thread, you will find it (and a standalone script) there again.

:huh:

How do you define a damaged file?

In running your script I come up with a total of 772 damaged files whic is probably about every dds file im my cache>

Hi Bob,

Sorry, it was my mistake. I dont scan for damaged files. I scan for damaged "file-pairs".
Explanation:
Every .dds-file is a compressed image of a little part of the world. It's saved in "... Cache\Earth\High-Resolution Terrain Mapped Imagery\"-subfolders.
Each (as I know) image comes together with a height-information - saved in a .tif-file in the "...Cache\Earth\TerrainTiles\"-subfolders.
This means:
If you have a .dds-file you can found the corresponding .tif-file (if youre looking in the right level). If you cant find the .tif-file - you (and World Wind) have no height information. On Level 0-1 or 2 its not the problem I think, because you cant see the heights, but on deeper levels you get "square-dance".
My script (and this of dsten) looks for this "lonely" .dds-files and delete them.
It can NOT fix the problem, if you have a damaged correspondig .tif-file.

I'll improve my little toolbox - so you will be able to select the levels to scan and perhaps the range.

I hope, I could help

Thanks for the explanation TuRRiCAN. It helps in my understanding about what is going on. I'm trying to identify the cause of problems I'm having in a few areas.

Hello,
for those who don't have Excel or other spreadsheet, I made a Javascript page, this includes also the calculation of coordinates from the tilename. Simply fill in and the calculations will be shown below. There are the tilenames with the full name, i.e. tilenames below 1000 will have leading 0, which would make it easier to search for them.
Look below at post #36 for the newest version.

Save the page with your browser for offline use.

Very neat app, better than my speadsheet.

[TuRRiCAN]

Respect canosso,
very nice converter.
But, you can't delete files - I know - these are limitations of javascript (and it's good so).
The best solution could be a plugin for WorldWind (or a solution by Worldwind itself). If Worldwind dont find its terrainfiles (while it tries to display it) why tries it not to download it again...

OK, I tried everything posted here, but I cant get any good results. Are these valid with the 1.3 version?

For example, I have file 0432_0858.jpg from \cache\Earth\High Resolution Imagery\NLT Landsat7 (Visible Color)\4\0432

World Wind says its bottom left coordinates are aprox Lat -29.25 Lon -59.35

Using all the methods described above (excel files, my own excel file, jscript page , I get Lat -36.00 Lon -72.75

All I want is to calculate the four corner coordinates of level 4 NLT Landsat cache files.

Any pointers?
