144 ==========================
145 Gdal_merge
146 ==========================
147 **What it does**
148
149 This utility will automatically mosaic a set of images. All the images must be in the same coordinate system and have a matching number of bands, but they may be overlapping, and at different resolutions. In areas of overlap, the last image will be copied over earlier ones.
150
151 |
152
153 **How to use it**
154
155 Select as much raster files as you want from history to make the mosaic.
156
157 Specifiy output format using short name (http://www.gdal.org/formats_list.html).
158
159 |
160
161 **Other options, advanced usage**
162
163 *-co NAME=VALUE*
164
165 Creation option for output file. Multiple options can be specified. See format specific documentation for legal creation options for each format
166
167 |
168
169 *-ot datatype*
170
171 Force the output image bands to have a specific type. Use type names (i.e. Byte, Int16,...)
172
173 |
174
175 *-ps pixelsize_x pixelsize_y*
176
177 Pixel size to be used for the output file. If not specified the resolution of the first input file will be used.
178
179 |
180
181 *-tap*
182
183 (target aligned pixels) align the coordinates of the extent of the output file to the values of the -tr, such that the aligned extent includes the minimum extent.
184
185 |
186
187 *-ul_lr ulx uly lrx lry*
188
189 The extents of the output file. If not specified the aggregate extents of all input files will be used.
190
191 |
192
193 *-v*
194
195 Generate verbose output of mosaicing operations as they are done.
196
197 |
198
199 *-separate*
200
201 Place each input file into a separate band.
202
203 |
204
205 *-pct*
206
207 Grab a pseudo-color table from the first input image, and use it for the output. Merging pseudo-colored images this way assumes that all input files use the same color table.
208
209 |
210
211 *-n nodata_value*
212
213 Ignore pixels from files being merged in with this pixel value.
214
215 |
216
217 *-a_nodata output_nodata_value*
218
219 Assign a specified nodata value to output bands.
220
221 |
222
223 *-init "value(s)"*
224
225 Pre-initialize the output image bands with these values. However, it is not marked as the nodata value in the output file. If only one value is given, the same value is used in all the bands.
