| 1 | STATUS:
|
|---|
| 2 | The i.ortho.photo suite of modules has been temporarily disabled
|
|---|
| 3 | from GRASS 7 as they are heavily dependent on the text-based
|
|---|
| 4 | Vask library and interactive XDRIVER monitors, both of which
|
|---|
| 5 | have been removed. As the modules are rewritten to run in non-
|
|---|
| 6 | interactive mode or with a wxPython frontend, they will be
|
|---|
| 7 | added back into GRASS 7. This work will be undertaken in the
|
|---|
| 8 | trunk SVN.

| 10 | AUTHORS:
|
|---|
| 11 | The orthophoto rectification programs went out under alpha in 4.0.
|
|---|
| 12 | It has since had bug fixes performed by OGI (Shapiro?) and also by
|
|---|
| 13 | the original programmer - Mike Baba of DBA Systems, Fairfax, VA.

| 56 | GRASS GIS 4 to 6
|

| 57 |
|
|---|
| 58 | The main program is i.ortho.photo which is just a menu driver for the
|
|---|
| 59 | following programs:
|
|---|
| 60 |
|
|---|
| 61 | 1 i.group
|
|---|
| 62 | 2 photo.target
|
|---|
| 63 | 3 photo.init
|
|---|
| 64 | 4 photo.camera
|
|---|
| 65 | 5 photo.elev
|
|---|
| 66 | 6 photo.2image
|
|---|
| 67 | 7 photo.2target
|
|---|
| 68 | 8 photo.rectify
|
|---|
| 69 |
|
|---|
| 70 | The following GRASS 6 directories contain the source code:
|
|---|
| 71 |
|
|---|
| 72 | ./menu: main menu code (-> menu/menu.c)
|
|---|
| 73 |
|
|---|
| 74 | ./photo.target: select target location and mapset
|
|---|
| 75 |
|
|---|
| 76 | ./photo.elev: select elevation model
|
|---|
| 77 |
|
|---|
| 78 | ./photo.camera: select a camera to use for parameters
|
|---|
| 79 |
|
|---|
| 80 | ./photo.2image: code for image to photo coordinate
|
|---|
| 81 | transformation
|
|---|
| 82 |
|
|---|
| 83 | ./photo.init: choose initial camera exposure station
|
|---|
| 84 | parameters
|
|---|
| 85 |
|
|---|
| 86 | ./photo.2target: computes photo to target location
|
|---|
| 87 | transformation parameters
|
|---|
| 88 |
|
|---|
| 89 | ./photo.rectify: does the actual image rectification
|
|---|
| 90 |
|
|---|
| 91 | ./libes: libraries for ortho programs
|
|---|
