Ezigrade 4.2.177

We have added in an "Adaptive Grid" data thinning. Very useful for Lidar and other big data sets. Adaptive grid thinning reduces the number of points in a surface by first overlaying a regular grid across the dataset and selecting a small number of representative points within each grid cell, typically the highest, lowest, and optionally the point nearest the cell centre. Boundary and protected points are always retained. A new triangulated surface is then constructed from this reduced point set and compared with the original surface. Where the vertical difference between the two surfaces exceeds a specified tolerance, additional original points are inserted to improve the local surface representation. This process is repeated in several passes until the surface meets the required accuracy or a maximum number of iterations is reached, resulting in a significantly smaller dataset that preserves the essential geometry of the original terrain.

Ezigrade 4.2.144

Ezigrade can now import a ".ezigrade" file produced for levelguide. A good check on what you are actally sending out. Bug in the Haulage arrows fixed. Sometimes it was not doing the whole job. When doing a grading job with sections hinged together. We now have an option on whether you want all the sections hinged together to try and maintain there cut/fill ratio or simply conform to a common cut/fill ratio for all the sections together. We will add an entry to FAQ's with more details.

.GPS viewer

>GPS viewer now migrated to Azure maps and is working without nags.

CDS 4.2.0.29

CDS background image's will now load. (After BingMaps was deprecated by Microsoft)

Ezigrade 4.2.142

We have migrated the background images from BingMaps to Azure Maps. BingMaps is no longer supported by Microsoft. Legacy Ezigrade programs will still display background images on old jobs; but New jobs will not be able to download background images. Please download the latest version to keep using background images.

Ezigrade, CDS and .GPS viewer

We have been using Google Bing Maps for background views. Apparently from June 30 2025 Microsoft is no longer supporting BingMaps and the service is now inactive. Thus background maps are either not displayed or have a watermark for the .gps viewer. We are migrating to the equivalent Microsoft Azure maps product. We will let you know when updates are available.

Ezigrade 4.2.141

When doing a pipe design and showing the profile pane. We now display a catchment value. This allows users to check the pipe diameter with online calculators that need the catchment area entered.
