There is Open Drone Map, that calls itself "Open Source Toolkit for processing Civilian Drone Imagery".
You can run it in docker container and you will get your own aerial photography service in the cloud.
Or you could try DroneDeploy cloud service, you can upload your photos to their cloud and get up to 5 maps for free per month.
Besides just getting orthomosaic photo, you can also get elevation maps and 3D maps which will blow your mind.
ImageMagick
supports: Large image support: read, process, or write mega-, giga-, or tera-pixel image sizes.
command --line will the most efficient way to do this:
(via -layers method)
merge
As 'flatten' method but merging all the given image layers to create a
new layer image just large enough to hold all the image without
clipping or extra space. The new images virtual offset will preserve
the position of the new layer, even if this offset is negative. The
virtual canvas size of the first image is preserved.
Caution is advised when handling image layers with negative offsets as few image file formats handle them correctly. Following this operation method with +repage will remove the layer offset, and create an image in which all the overlaid image positions relative to each other is preserved, though not necessarily exactly where you specified them.
See also 'trim-bounds' below which is closely related but without doing the'flatten' to merge the images together.
mosaic
As 'flatten' method but expanding the initial canvas size of the first
image in a positive direction only so as to hold all the image layers.
However as a virtual canvas is 'locked' to the origin, by its own
definition, image layers with a negative offsets will still become
clipped by the top and left edges. See 'merge' or 'trim-bounds' if
this could be a problem. This method is commonly used to layout
individual image using various offset but without knowing the final
canvas size. The resulting image will, like 'flatten' not have any
virtual offset, so can be saved to any image file format.

You might want to look at Microsoft ICE. Its free, but its not a geospatial solution. I have used it with good success. It will make a good mosaic, and then you can reference the mosaic.
The best (commercial) product I have encountered for mosaicing images is Erdas Imagine's Mosaic Pro (MP). There are several features of MP that I particularly like:
- MP utilizes all of the cores of your machine.
- Handles > 2.5 TerraPixels and thousands of images
- There are a variety of seamline and overlap rule options available
- There is a good variety of output formats
- You can create new subtiles based on a shapefile
- You get access to the rest of Erdas's functionality
Copan Lite should do exactly what you need. It's a free, GUI-based Windows COGO tool for land or topographic surveyors. (I was heavily involved in its development.)
From the Field Bearings Processing section of the User Manual:
Use this module to process raw field data from hand-held survey
instruments such as compass, inclinometer and rangefinder. Copan can
process the data — azimuths (or bearings), vertical angles, slope
distances, and instrument and signal (or target) heights — whether
concerning one or more connected traverses, independent radial
surveys, or combinations thereof, to calculate new points. Data may
come from data logger files or be manually input from field books.
Traverses may be adjusted for coordinate misclosure and new points may
be saved.

I would recommend either Qrule or SIMMAP. The suitability of a given model is dependent on what type of neutral landscape structure you wish to simulate (e.g., edge fractal dimension, mean patch size, juxtaposition, etc...).
Qrule: http://www.umces.edu/al/program/gardner/qrule
SIMMAP: http://www2.montes.upm.es/personales/saura/software.html
I am not sure what tools you are looking for (not sure what do you want to simulate) but there are few programs that deal with landscape indices:
Fragstats - http://www.umass.edu/landeco/research/fragstats/fragstats.html
Patch Analyst - ArcGIS add-on (link to presentation - http://www.cnr.uidaho.edu/rsgis/docs/Fragmentaiton.pdf)
GRASS GIS have a module for this- r.le or r.li.
SAGA GIS may have some tools, depending what indices you want to calculate (http://www.saga-gis.org/en/index.html).
LandFrag - is something you may have a look at as well (http://placeways.com/products/landfragtool.php)
Placeways does have also software that allows for more extensive calculation, so have look at theirs site.
