| 125 | | G7:i.atcorr now includes support for the atmospheric correction of 7 new satellite images: Pleiades1a, Pleiades1b, Spot6, Spot7, Sentinel-2A, Rapideye, Worldview3 and mod09GA QA definitions was added to G7:i.modis.qc. In addition to the already existent region growing algorithms, G7:i.segment now also includes mean shift. |
| | 124 | New: |
| | 125 | |
| | 126 | * G7:i.segment: new mean shift algorithm |
| | 127 | * G7:i.atcorr: added support for Pleiades1a, Pleiades1b, Spot6, Spot7, Sentinel-2A, Rapideye, Worldview3 |
| | 128 | * G7:i.modis.qc: Added mod09GA QA definitions |
| 142 | | In the past year of development, there were several changes in different GRASS GIS libraries. The most relavant changes are described below: |
| 143 | | * In the rasterlib there is now NULL file compression by default. |
| 144 | | * The temporal framework has now support for spatial topological operators to the temporal algebra, several tests were added as well as a new function to convert granularity to a smaller granularity, and raster region specific parallel processing has been enabled by means of the MultiModule new class in PyGRASS. |
| 145 | | * projlib now provides improved integration of GDAL and streamlining of spatial reference system handling, as well as new functions (GPJ_grass_to_wkt2 and GPJ_grass_to_osr2) |
| 146 | | * libgis has received several major and minor enhancements. There are new functions such as G_adjust_window_ll to automatically fix lat-lon errors and the lat-lon restrictions when reading DMS coords were relaxed. On the other hand, G_window_percentage_overlap now accounts for N == S or E == W. The function G_compare_projections has an enhanced ellipsoid check. Moreover, BZIP2 compression has been improved for speed and support for HTML/CSS hash hexadecimal colors has been added in G_str_to_color. |
| | 145 | * Temporal framework: |
| | 146 | * Implemented temporal algebra complement tests that show the current condition bugs |
| | 147 | * Added spatial topological operators to the temporal algebra (r71369) |
| | 148 | * Tests regarding implicit temporal aggregation |
| | 149 | * improved gran_to_gran function to return correctly years and second values |
| | 150 | * added function to convert granularity to a smaller granularity |
| | 151 | * Enabled raster region specific parallel processing by using the MultiModule class |
| | 152 | * projlib: |
| | 153 | * improved integration of GDAL and streamlining of spatial reference system handling |
| | 154 | * added GPJ_grass_to_wkt2() and GPJ_grass_to_osr2() |
| | 155 | * improve creating new spatial reference from embedded proj4 definition |
| | 156 | * python vector scripting library: |
| | 157 | * added layer variable to vector_info and vector_info_topo functions |
| | 158 | * libgis: |
| | 159 | * G_window_percentage_overlap() now accounts for N == S or E == W |
| | 160 | * new G_adjust_window_ll() to automatically fix lat/lon errors |
| | 161 | * relax ll restrictions when reading DMS coords |
| | 162 | * support for HTML/CSS hash hexadecimal colors in G_str_to_color() |
| | 163 | * G_compare_projections(): compare unit names only if there is no to meter conversion factor |
| | 164 | * speed improvement for bzip2 compression |
| | 165 | * ignore case when comparing units in G_compare_projections() |
| | 166 | * G_compare_projections(): enhance ellipsoid check, combine standard parallels |
| | 167 | * rasterlib: |
| | 168 | * fix/improve Rast_align_window() |
| | 169 | * simlib: |
| | 170 | * more control over seeding for random number generator |
