4 Introduction Geoverse Convert converts many types of point cloud and polygon data into the Unlimited Detail streaming format (UDS) and Unlimited Detail Grid format (UDG). Supported source formats include: Fully supported: uds, las, laz, bin, e57, xyz, csv, txt, ptx, pts, llargbin, fls, fws Partially supported: ply, obj See Supported File Formats for more details Expected conversion speed is around 3.5 billion points per hour for binary data and 1.5 billion points per hour for text data. (1 Million points a sec for binary and 400,000 for text). NOTE : Geoverse Convert does not currently operate on a 32bit system. The Geoverse Convert User Interface 2

5 Job Settings The Job Settings Control INPUT FILES To get started simply drag and drop files to convert into the Input files area (or use the Add files button). NOTE: Your source data cannot have file names with Unicode characters OUTPUT TYPE Euclideon Data Set (UDS) The most common output format; creates one UDS file per job upon job completion. Euclideon Data Grid (UDG) Used for very large data sets; creates one UDG file and multiple UDS files in a sub-directory. VERSION For Geoverse MDM 1.1+ Creates files that are compatible with Geoverse MDM 1.1 onwards. For Geoverse MDM 1.2+ Creates files that are compatible with Geoverse MDM 1.2 onwards. Note: Geoverse MDM is backward compatible allowing you to open all the UDS file versions in the latest release. OUTPUT FILE Set the name and directory for the output file. 3

6 USE COMPRESSION Use this option to further compress output files. This will increase conversion time. Compression is only available for Geoverse MDM 1.2+ output files. GEOMETRY UNITS The geometry units are required to be set to the same unit type as what the input data uses; before converting it is advised to test a small sample first to verify the settings are correct. You can export just a small sample of your data by assigning a Maximum Number of Points. If you register an Existing GIS Projection which specifies unit type, it will automatically choose the correct Geometry Unit for you. RESOLUTION Set the physical size for each point; before converting it is advised to test a small sample first to verify you are happy with the settings. DESIRED GRID SIZE (ONLY USED FOR UDG FILES) Specify the desired size of each grid. Upon job completion each grid square will be the dimensions of a separate UDS file. ACTUAL GRID SIZE (ONLY USED FOR UDG FILES) Geoverse Convert will advise of the closest possible matches to the desired grid size; possible grid sizes are always a power of two. Please select the closest possible match to the desired Grid size. It is recommended to use a UDS file where ever possible. Only switching to a UDG file when the point to data set scale exceeds 1 : 1,000,000 (six orders of magnitude) Point Size : Data Scale 1mm : 1km ~ Approx 1/16 point size : ~ Approx 1 mile *(1mm=1x10-3 m 1km=1x10 3 m) It is possible to continue using UDS files for large data sets however users may experience vibrating points when trying to view the data in close detail. Additional Output files JOB SETTINGS FILE: A Job Settings file with the file name <InsertJobNameHere>.JobSettings will be saved out for each completed conversion. Each file is in ASCII format and the file contains details for that particular job. You can drag and drop this file into Geoverse Convert Job List to update or repeat the conversion. JOB LOG FILE: A Job Log file with the name <InsertJobNameHere>.JobLog will be saved out for each job conversion. Each file is in ASCII format and the file contains details for that particular job. 4

7 Advanced Job Settings The Advanced Job Settings Control Before converting, there are some additional advanced settings that can be used. Click on the Advanced tab to access these. Data Processing MAXIMUM NUMBER OF POINTS This option limits the number of input points that Geoverse Convert will convert. If you are converting a large data set, it is recommended to process a small section of data first (i.e. 1,000,000 points) to ensure that the point size and other options are correct. EXPORT INTENSITY Enabled this option if the source data has intensity values and they will be included in the output UDS file. If the source data does not have intensity information the output will be given a value of 0. EXPORT CLASSIFICATION Enabled this option if the source data has classification values and they will be included in the output UDS file. If the source data does not have classification information the output will be given a value of 0 (never classified). Point GIS Transform Point GIS Transform enables you to convert the source data from one GIS space to another during conversion. This is often necessary if the data is in Latitude/ Longitude format as Geoverse MDM requires a Cartesian projection. Existing GIS Projection specifies the source projection of the incoming data (typically WGS84 for Latitude/Longitude). Output Transform specifies the final coordinate system to be used in the 5

8 converted file. If the data is already in the required projection you can simply specify this field to tell Geoverse products the projection of the data, for example this is typically an EPSG code. For example; if your source data is Latitude/Longitude and is from the East Coast of Australia, you would be using WGS84 as existing projection and Output Transform as EPSG: GIS Transform assumes the data set is Longitude/Latitude; the Reverse XY allows you to input data that is Latitude/Longitude. Color COLOR FORMAT The precision of how the data is stored in the final data set. Trading size for accuracy. RGB 8 palette is typically fine for most datasets. Selecting Grayscale will source the color from the point intensity values and will activate the intensity range options. 24-bit RGB 16-bit RGB 8-bit RGB (Palette) 8-bit Grayscale intensity INTENSITY SCALE If the source data has only intensity values, these options will specify the valid intensity range to convert to a gray-scale color. The minimum value represent black, and maximum value represents white. Intensity values are sourced in the range of 0 to (16 bit). Source data formats that are not in this range are re-scaled to 16 bit. Metadata WATERMARK FILE You can provide an image file here which will appear as a watermark over your screen when viewed in Geoverse MDM. Images supplied will be rescale to maximum size of 256 x

9 File-specific options Some file types allow for extra configuration options. When you bring these files into a Job s Input Files list, a tab will appear with that file s specific options..las/.laz Options LAS COLOR RANGE The min and max range of the color values to be expected in the file. SWAP 16BIT BYTE ORDER Colors with 16bit per channel can be interpreted with the order of the 8bits swapped. GAMMA CORRECT Apply a gamma correction to the input colors..obj Options LIGHTMAP A lightmap is an image used to generate false lighting for converted OBJ files. This helps give the converted UDS file a more realistic appearance. Geoverse Convert is bundled with a lightmap if you do not have one, it is located inside the directory that you installed Geoverse Convert to. TEXTURE MEMORY SOFT LIMIT This limits the amount of memory (RAM) that will be used to store images during the conversion process. 7

10 Jobs The Job List This panel shows the current progress and status of existing jobs, including detail relating to Status, Conversion Time, Number of Points and Progress bars. It is possible to add and remove jobs, as well as start and stop the conversion process using the on-screen buttons. You can cut, copy and paste jobs, as well as add.jobsettings files from previous conversions. FILE LOG Records important events, errors and notifications that have occurred during the conversion process. If your conversion fails, make sure you check the file log to ascertain the reason. Geoverse Convert Settings DEFAULT OUTPUT DIRECTORY The default directory where the.uds /.UDG files will be saved for new Jobs. INTERMEDIATE DIRECTORIES During the conversion process temporary data will need to be stored before the data is converted to the final format. Choose a location for intermediate directory(s) here. For a faster conversion we recommended a different physical drive for each intermediate directory. It is recommend too have double the data set size as free space on your selected hard-drive; this will be used for the creation of temporary files during conversion (a 10 GB data set should have 20GB free storage space.)

11 Command Line Options You can start Geoverse Convert through the command line by specifying a jobsettings file and the /start argument. C:\Users\User> Start by either navigating to or locating the GeoverseConvert.exe. By default, this is located in C:\Program Files\Euclideon Geoverse Convert\ C:\Users\User>cd C:\Program Files\Euclideon Geoverse Convert\ Enter GeoverseConvert.exe, followed by your.jobsettings file and the /start argument....>geoverseconvert.exe D:\Sample.jobSettings /start ARGUMENTS /start This argument tells Geoverse Convert to start the job immediately. If you omit this argument, Geoverse Convert will load the job settings then wait for regular input. /y Suppresses prompting to confirm you want to overwrite an existing output file. 9
