Python and Java API / Split in Chunks Script Fails on Empty Chunk

« on: July 02, 2019, 08:14:55 PM »

Hi,

I am using the split in chunks script to process 10,000 aerial images. All cameras were aligned and optimised in a single chunk and I selected a 5x5 split in the script dialog. Due to the geometry of the project the script created a chunk with no data and processing subsequently failed - is this expected? I have resized the original bounding box and changed the split to 3x6 which hopefully won't have any empty chunks. Is there any way to restart the script without losing the data that's already been processed? Also, how do you set the dense cloud filtering options?

Thanks,

Rory

General / RGB DEM Palette

« on: June 13, 2019, 04:38:59 PM »

Hi,

We are working on a very large project of over 20,000 hectares and delivering height-field models, DEMs (32bit and RGB) and orthos. The site is broken down into sections by individual flights (approx 600 - 800 images) and we would like to export the RGB DEMs with the same height palette, i.e. the absolute height colours are the same on every individual DEM.

I can do this by colourising the 32bit DEMs in ArcGIS or QGIS then exporting them as RGB tiffs but it's a huge amount of extra work, is there a way to specify the height colours in Metashape Pro when exporting a palletised DEM?

Thanks,

Rory

Bug Reports / Incorrect Elevations in Report

« on: February 26, 2019, 01:12:21 AM »

When exporting the processing report the elevation scale on the DEM is way off, although the scale is correct when viewing the DEM in Metashape. This is using Metashape 1.5.1 on MacOS Mojave.

I've only noticed this since 1.5.1. I can edit the report in Acrobat to change the heights but not ideal.

General / New Workstation for Metashape

« on: January 25, 2019, 02:01:37 PM »

Hi,

We are a Mac based organisation but looking to build a Windows workstation purely for Metashape. Just wanted to sanity check our spec before we go ahead and order. We work with aerial datasets with sites up to a maximum of 100ha and GSDs between 2 and 5cm/px. The bulk of our jobs are smaller, with 200 - 500 images. The PC spec we're looking at is:

Intel i9 9900X 10 core 3.5GHz/4.4GHz
ASUS TUF X299 motherboard
128GB Corsair Vengeance LPX 3000MHz
2 x 8GB EVGA  GeForce RTX2080 Black Edition
500GB NAND Samsung 970 EVO
4 x 4TB Seagate Firecuda (RAID 1+0)

We're looking at at least a 3 year ROI on this hardware. Do you think this is a good spec?

Thanks,

Rory
