3D Modeling with High Resolution LiDAR

I created and presented this poster featuring LIDAR Color Shaded Relief model of Bouctouche / Shediac area of New Brunswick at the 2004 Geotech event that was held in Toronto.

UTM Rows and Zones

These UTM key maps can easily help you find out what UTM zone you are working from. Simply click on the map to enlarge it to expose all of the map, then find out where you are located and look for the zone and row that matches your area.

Using Google Earth to obtain NGS CORS Information

Every now and then I come across some little utilities that help to make things easier while working in the field and these pages are mainly my way of sharing them with others while creating a go-to place where I can easily find them when I need them.

Here is a Google Earth file that that contains locations and basic information about all of the National Geodetic Survey (NGS) Continuously Operating Reference Stations CORS. Saving you time from searching for CORS stations in your area and finding out what sampling rate they record GPS data at.

Bouctouche New Brunswick LIDAR

I created and presented the following poster displaying LIDAR CSR surface modeling of Bouctouche, New Brunswick as part of my Applied Geomatics graduate work at COGS in 2004.

Color Shaded Relief Models

A color shaded relief (CSR) utilizes chromo stereoscopic techniques to help emphasize the depth of the Z dimension from traditional shaded relief models that already portray the presence of an elevation difference. Using carefully edited …

Digital Elevation Models (DEMS)

A digital elevation model (DEM) or sometimes referred to as a digital terrain model (DTM) is a quantitative representation of the topography of the Earth. DEMs are used as a source of elevation (and to create other digital terrain models) for many different purposes

Digital Terrain Modeling

Digital Terrain Modeling is the process of simulating or representing the relief and patterns of a surface with numerical and digital methods. It has always been an integral component to geology related fields such as geomorphology, hydrology, tectonics and oceanography but over the past decade has also become a major component to non geophysical applications such as GIS modeling, surveying and land use planning.

Terrain Models are derived from data represented by digital elevation models (DEMs) and can include shaded relief models, slope and aspect models, perspective scene generation, and drainage basin analysis (and other models).

3D Flood Modeling with LIDAR

The main goal of this project was to generate flood maps and DEMs with better than 30 cm vertical accuracy for the coastal area of southeastern New Brunswick.
