Datasets¶

The Datasets module lists all of the datasets that have been both uploaded to and created within SpatialScale.

Dataset List View¶

Image of dataset page

Name¶

The name that the dataset was given at the time of upload/creation. To view additional details about your dataset, click on the name and you will be redirected to the Dataset Overview page.

Type¶

Displays the type of data in your dataset.

Status¶

The status column indicates which step along the processing workflow the dataset is currently in.

Size¶

Size of dataset in cloud storage.

Last Update¶

Displays the date that the dataset was last modified, or the date of upload if no modification was performed.

The Edit button opens the Update window.

The Delete button permanently removes this uploaded dataset from your list of datasets. You will be asked twice to confirm the removal of the dataset. This will clear space in your upload quota.

Datasets Search Bar¶

Enter the name of a dataset in the Filter/Search Bar to narrow it down to datasets with just that text in the name.

Data Upload¶

Accepted File Formats¶

SpatialScale accepts LiDAR point clouds, raster imagery, and vector files in the formats listed below.

File Type	Details
.geojson	single GeoJSON file
.las / .laz	classified or unclassified
.shp	zipped into one file (not folder)
.tif / .tiff	1-band 8-bit type, 3-band 8-bit type, 4-band 8-bit type, 1-band palette color

For .tif/.tiff files, band 4 will only be included if it is set as ‘Alpha’ Color Interpretation. Otherwise, all bands labeled 4 and higher will be ignored for web visualization. Additionally, please note that SRID information must be supplied in the header and/or metadata of these files, or alternatively entered during the data upload step.

Dataset Details¶

Dataset Overview¶

Clicking on the dataset name will bring you to the Dataset Overview page, where you can view details and access additional functionality.

The original files are listed below the description and the About this dataset panel to the right of the Description box displays additional details.

Clicking Edit will open the Update your Dataset window.

Update Your Dataset¶

The Update your Dataset window is where you can:

rename your dataset
edit the Description

Once you fill in the details and click Save, the details will be visible on the Dataset Overview page.

Package / Download Data¶

Point clouds, rasters, and some vector datasets can be packaged for download on their respective Dataset Overview page. Click the Create Package button. A popup will notify you that the packaging is in process.

The button will grey out while it is Packaging Data, and will be available once more when the Download Package option is ready.

Jobs¶

Point Clouds¶

Classify Points¶

In the Classify Points job, SpatialScale will declassify the original data and reclassify it for you. During this process, the calculations use the classified ground points in the LiDAR data as a reference to generate products.

Change Distance¶

Conduct a change detection analysis between two point clouds using cloud-to-cloud distance. A new column is added to the result point cloud with the change distance. The distance of the reference (old) point cloud from the comparison (new) point cloud is negative and comparison (new) point cloud from the reference (old) point cloud is positive.

Colorize Points¶

Colorize point clouds using input values read from a raster dataset.

Digital Elevation Model (DEM)¶

The Digital Elevation Model (DEM) job enables you to create either a DSM (Digital Surface Model) or DTM (Digital Terrain Model) from points.

Rasters¶

Aspect¶

Create an aspect raster dataset with pixel values ranging from 0-360 indicating azimuth from any DTM/DSM image.

Hillshade¶

Create a shaded relief dataset from any DTM/DSM image.

Surface Roughness¶

Create a surface roughness dataset from any DTM/DSM image.

Slope¶

Create a slope dataset from any DTM/DSM image.

Terrain Ruggedness Index (TRI)¶

Create a Terrain Ruggedness Index (TRI) raster dataset from any DTM/DSM image.

Topographic Position Index (TPI)¶

Create a Topographic Position Index (TPI) raster dataset from any DTM/DSM image.

Vector¶

Point to Hex¶

Generate a hex grid based on point shapes.
