Scripts for GIS by Luiz Motta

  • This package consists of a number of scripts utilities for use in conjunction with GDAL and tilers-tools.
  • Started: 2015-03-05
  • Version: 0.1

Scripts

2_rgb.sh

  • Create RGB image (Ex.: image_r3g4b5.tif)
  • Dependencies: gdal 1.10.1 (gdal_translate)
  • Example (using parallel):
    nohup parallel 2_rgb.sh {} 2 4 5 < LIST_OF_IMAGES

16b_2_8b_convert.sh

  • Convert images of 16 to 8 bits (overwrite original file)
  • Dependencies: gdal 1.10.1 (gdal_translate, gdalinfo, gdalbuildvrt)
  • Example (using parallel):
    ls -1 *.tif | parallel 16b_2_8b_convert.sh {}
    nohup parallel 16b_2_8b_convert.sh {} < LIST_OF_IMAGES

16b_2_8b_convert_kdialog.sh

  • Using Kdialog (KDE)
  • Dependencies: 16b_2_8b_convert.sh

check_error_img.sh

  • Check error for read image(print ERROR if exist error)
  • Dependencies: gdal 1.10.1 (gdalinfo)
  • Example (using parallel):
    nohup parallel check_error_img.sh {} < LIST_OF_IMAGES

check_overlaps.py

  • Check overlap inside shapefile
  • Dependencies: gdal, python-gdal
  • Create CSV files: name_shapefile_overlap.csv, name_shapefile_invalid.csv, name_shapefile_empty.csv
    check_overlaps.py --multiproc name_shapefile
  • Example(using multiprocessing):
    check_overlaps.py --multiproc name_shapefile

create_gdal_tms_target_window.sh

  • Create GDAL_WMS file (XML) from image with no standard TAG
  • Dependencies: gdal 1.10.1 (gdalinfo, ogr2ogr)
  • Example:
    create_gdal_tms_target_window.sh [IMAGE] MAX_ZOOM

footprint.sh

  • Create GeoJson with border's polygon of image (limited with valid pixels)
  • Dependencies: gdal 1.10.1(gdal_calc.py, gdal_sieve.py, gdal_edit.py and gdal_polygonize.py)
  • Example (using parallel):
    nohup parallel footprint.sh {} < LIST_OF_IMAGES

footprint_kdialog.sh

  • Using Kdialog (KDE)
  • Dependencies: footprint.py

footprint_add_url_tms.sh

  • Add URL of TMS in footprint(GeoJson) * NOT USE for others Geojson
  • Dependencies: None
  • Example (using parallel):
    nohup parallel footprint_add_url_tms.sh {} http://10.1.8.20/test_lmotta < LIST_OF_IMAGES

footprint_convexhull.py

  • Create convexhull from Geojson (used to soften the footprint)
  • Dependece: GDAL Python bindings 1.10.1
  • Example (using parallel):
    nohup parallel footprint_convexhull.sh {} < LIST_OF_IMAGES

footprint_convexhull_kdialog.sh

  • Using Kdialog (KDE)
  • Dependencies: footprint_convexhull.py

footprint_extent.py

  • Create extent of image16b_2_8b_convert
  • Dependece: GDAL Python bindings 1.10.1
  • Example (using parallel):
    nohup parallel footprint_extent.sh {} < LIST_OF_IMAGES

footprint_extent_kdialog.sh

  • Using Kdialog (KDE)
  • Dependencies: footprint_extent.py

footprint_append_shp.sh

  • Adds the footprint (GeoJson), all Geojson, inside shapefile (if not exist it is created)
  • Dependencies: gdal 1.10.1(ogr2ogr)
  • Example (NOT USE parallel!):
    for item in $(ls -1 *.geojson); do footprint_append_shp.sh $item LC8_footprint.shp; done

gdal_thumbnail.sh

  • Create thumbnail file(PNG) from image
  • Dependencies: gdal 1.10.1(gdal_translate)
  • Example (use parallel!):
    nohup parallel gdal_thumbnail.sh {} 30 < LIST_OF_IMAGES

mk_tiles.sh

  • Create TMS structure (directories and files) and XML for GDAL_WMS driver from image
  • Dependencies: dans-gdal-script 0.23-2(gdal_contrast_stretch), tilers-tools 3.2.0(gdal_tiler.py), gdal_thumbnail.sh
  • Example (use parallel!):
    nohup parallel mk_tiles.sh {} 2 17 ./png ./tms http://10.1.8.20/test_lmotta < LIST_OF_IMAGES

ls_img_lst.sh

  • Count the number of items in lists in current directory
  • Dependencies: None
  • Example:
    ls_img_lst.sh
