General / GCP questions:
« on: January 19, 2017, 05:17:57 PM »
1:  the checkbox left  to a marker (to left for "long,lat,alt,accuracy,error"...)    - does it enable/disable a given GCP for processing ?

2: if there is a marker, (GCP) , but it is not placed in any photo ( "it's icon is not green, but grey")  does it have any influence on the processing ?

3: is it possible to have a marker only be used for altitude only ? (aka - the position is +/- 10meters, but we know that flat area had a given altitude of meters)

4: imagine all photos for a map contain ellipsoid (GPS) altitude, then we add some GCP's with local geoid corrected altitude, - is the result expected to be "good" ?  - or does all altitudes, (in exif too)  - need to be geoide corrected ?

1: please add an action "create directory"
before exporting tiled data, it would be very nice to be able to
mkdir {projectfolder}/Tiledoutput

2: please add "enable/disable" checkbox per script action
When using complex scripts that are supposed to do a lot, from start to end, - you may sometimes do something, or want to do something manually.   
So it would be very useful if we could just disable (skip) steps , without altering the script.

General / Is batch with relative paths/names possible ?
« on: November 16, 2016, 04:04:08 PM »
my projects are usually in own folder:
~/photoscan projects/placename/placename.psx

making a batch that ends with multiple exports, is hard, because every export needs it's path, like:
import photos from:
~/photoscan projects/placename/photos/*
~/photoscan projects/placename/placename-orto/placename-orto.tiff
~/photoscan projects/placename/placename-dem/placename-dem.tiff
~/photoscan projects/placename/placename-las/placename.las

I miss the possibility to script something like:
# %pname% is the name of .psx file
# %ppath% is the path of the .psx file


This way . a script would be perfectly re-usable between projects.
this way - the same batch could be used on every dataset, and

an attempt to load w/o the .sh file shows that:
$ ldd ./photoscan |grep png => /usr/lib/x86_64-linux-gnu/ (0x00007f2394b10000)

$ ./photoscan
./photoscan: error while loading shared libraries:

executing the .sh file gives the error in subject.

Feature Requests / "Surface extraction"
« on: August 04, 2016, 12:17:50 PM »
Is there a feature that can rutomatically remove objects/trees from DEM data ?

If I add a csv containing EPSG::25833 markers ,selecting in the import dialog that coordinate system, it will show up in the marker list, but *no* markers will be in the map correct area.

If I convert the .csv markers to ESPG::4326, using gdaltransform, then import it as EPSG::4326  - it'll work properly.

Somehow, "Import CSV" dialog - does not really treat the coordinates as EPSG::25833.

I have rendered some maps.
Then added more GCP's. (and placed them in photos)

-which steps in the workflow need to be redone ?

General / Q about multi-level flights.
« on: June 27, 2016, 12:03:00 AM »
Imagine a dataset consisting of photos with 60% overlap,  *and* photos with barely any overlap,(lower altitude).

Question: Will the closer to the ground photos still be used to give good details because they can be aligned using the higher-altitude photos ?   - will the map be better ?

General / Question about adding GCP to an "completed"
« on: June 26, 2016, 11:59:13 PM »
I have made some maps w/o GCP  - now I got GCP's.
how far back in the workflow do I need to go (what to repeat), in order to properly render it with GCP ?

Feature Requests / Please post application icon.
« on: April 19, 2016, 11:13:11 PM »
The application does have an icon, but please post a .svg , .png or other icon , and make it a standard part of the linux package,  That would make it easier adding a nice shortcut to the application.

Please add information about time use for completed steps like:

"Dense Cloud...  completed in 1h23m"

Feature Requests / Report time.
« on: April 15, 2016, 01:47:49 PM »
The Report provides a big time/date of the report time on the first page.
It would be nice if also checked EXIF when available, and said:

Data collected  20/4/2015 09:40  ..  12:30

giving a clue on when this job was done

Why is it so, that when "Align photos" step is done, it's still possible to get some more photos aligned, just by selecting them and clicking ~"align photo" ?

Why is that not done automatically ?

Please see photos, zooming in helps with more details about the map. (sorry for not taking screenshots, but I wanted the process to be as uninterrupted as possible)
Efter selecting to export as tiff og bigtiff, all RAM is hogged - then swapping to a fast 160GB SSD starts, ultimately it will be full, and the process fails.

Why ? - as I understand it, the data is already there, and it's just a matter of writing it to a file.
The whole dataset, with pictures and all the processed data, is only 40GB

Feature Requests / Please optimize geotif export
« on: December 19, 2015, 02:00:41 AM »
I can export geotif of huge/hires areas as tiles just fine.
- exporting to one .tif file file fails - it's "never" enough RAM for that.
please consider writing a tiled geotif - processing it as tiles, or export to tiles, then assemble to one big tif (in case that reduces the needed RAM)

I have 64GB RAM on Linux, with 96GB SSD Swap (which never gets close to filled anyway)
