  • Anyone perfectly connecting tiles?

    Rodeo

    so your saying the process is to create each tile one at a time.. make sure that we separate the files from each run of the geoconvert tool and then after the fact compare the files we created and snip any duplicates? what if we want to make a state worth of tiles and need hundreds of them to get the job done?

    This has to be the most convoluted and tedious process...

    Basically you'd need to create a directory for each image.. then read every file from every folder and keep a list of ones that show up more than once and trim out all those files from every "infected" folder?

    oi..

    Seriously?

  • What am I doing wrong with geo convert tool

    Quote from whitav8

    We each try the scenery generation with different ideas in mind. I find it simpler and faster to make large areas with 4 m per pixel resolution( which is OK at 2000 feet AGL or above ) and then make 2 nautical mile square or so high resolution areas around cities or airports. I did the entire state of Washington which is 200 nautical miles by 300 nautical miles that way . So FSET level three or four for lower resolution, TMC level 11 or 12, then FSET level 0 or -1 with TMC level 13. Actual airports are done as a 3D model with AC3D with a -1 FSET image as the base. The runway is a separate object as well as buildings and static airplanes and maybe trees

    How are you combining tilesets made in different runs of geoconvert? I always get a stupid low resolution border between tiles created in a different geo convert session

  • Releasing USGS JP2 to TIF/TFW converter exe

    You need to install osgeo4w (You just need GDAL) found here https://trac.osgeo.org/osgeo4w/

    Here is the link to the jp2 to tif program https://drive.google.com/file/d/0BzHmCf…iew?usp=sharing

    configure the maketif_config.txt file (make sure to keep double backslashes between folders C:\\myfolder\\mysubfolder\\

    click the maketif.exe or run from command prompt

    program reads in a folder of JP2s, converts them to tif, projects them to lat/long and at the end writes the tfw files.

    If i have some time this weekend I will have it make the tmc for the total area as well.

    Let me know if you have any questions or problems

  • USGS JP2 Converter Application Update

    @Jetjockey10 I am going to package up my USGS JP2 to TIF with TFW application. I'll get it to you this weekend.

    I need to work out a tile mask generation issue that i have come across.

    BUT!!!! Generating Tifs and TFW from usgs imagery is really easy if the tools are in place..

    DOWNLOAD AND INSTALL With Default Options!!! -- osgeo4w -- google it.. its there, get it for your particular brand of Windows

  • Question about mask files in adjacent tiles processed at different times

    Quote from drhotwing1

    It might be a good idea to add a trigger to turn this on and off maybe within the TMC file itself for those like you that want to produce sectors of scenery and combine them into a total area.

    Let me see if this is possible.

    That would be amazing!

    States and even parts of states are just too large to process in huge batches, it makes sense to divide and conquer as it were.

    Thank you for looking into this

  • TMC file coordinates format

    Quote from Hartman

    Thanks for confirmation.

    That's the reason I like TMC better than TFW. :)

    If you need a tool to create tfw for you i can have that to you by tomorrow, I have one that takes ~25 seconds to process a JP2 downloaded from the usgs into a TIF with TFW.. I am also working on the bit that defines the total TMC area for the dataset to be processed. program loops through a working directory and deposits them in a "done folder".... Maybe tonight since the wife is headed out to meet friends.

    You need to install osgeo4w.. I will create the exe.. you need to be able to modify a config file to point at the directories you are working with. (Of course the program is open source)

  • Question about mask files in adjacent tiles processed at different times

    Hello Geoconvert Devs,

    I have noticed that between blocks of imagery that have been processed in different batches of geoconvert there is a dead zone where neither is displayed, only the super low res base imagery.

    I am assuming this happens because of the mask files being overwritten from one geo convert batch to the next.

    What can i do about those extra mask files that are blocking what is otherwise good imagery..

    I have done some small tests where i process 8 multi image blocks of tiles each in their own geoconvert instance, one at a time. the end result is a grid pattern where the lines of the grid are low resolution and the spaces between the lines are my imagery.

    When you process those same 8 images as a unit in one geoconvert session everything is perfectly good.

    Any suggestions?

    Thank you!

    Sycosys,

    I know a user that surely could use something like this. So much USGS scenery, so many individual tfw files to hand make. duh.

    Regards,

    Ray

    As soon as i get this thing packaged into a gui and turned into an exe I am very excited to get this out to folks.. Im sure there are bugs and things i havent thought about but so far this is a huge time saver for big datasets and we will sort it out together.

    I had the wild thought of sorting out how to do this over distributed processing so i could get a handful of old machines loaded up with this software and have em start chewing away at the usgs repository.

  • USGS JP2 Converter Application Update

    Hello,

    Didn't want you to think i had quit working on this... quite the opposite. In the last couple days I have butchered hundreds of tiles. Learned a whole mess about exactly what we need in the geoconvert tool and found new and interesting ways to interact with applications that never meant to be run from another program (looking at you geoconvert) :)

    I still need to build a gui for this thing which will likely take another few days but it is stable and working well.

    I am currently testing on 8Km by 7Km, 1meter Naip Tiles, 450 of them.

    Here is a sample of the program output as it works through the steps.. and the attached screen captures show the various steps as I see them this moment. JP2toTIF, TIFtoLatLong and Finally Geoconvert/TilesEverywhere
