A new large 8 foot color shaded relief map that I have created has been posted for display at a local tourist kiosk in Advocate Harbour, Nova Scotia. Now both tourists and residents of the area will be able to gain a better appreciation of the topography that borders the Northern Bay of Fundy region
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 …
The above image is one of several color shaded relief (CSR) models I created of Gatineau foot hills of Quebec. The city of Ottawa is featured in the national capital region near the bottom center of the image across the river just south of Gatineau Park. This was one of the color shaded relief models submitted for use with an online interactive web GIS mapping project for the municipal of Collines-de-l’Outaouais, Quebec. The image below is the actual one that is currently featured in the web GIS project.
The Gatineau Hills are part of a geological formation in Canada which represent the foothills of the Laurentian Mountains which stretch east through Quebec, beginning north of Montreal and joining up with others into Vermont and New Hampshire. The geology of Gatineau Park, which encompass these foothills, is related to the Eardly Escarpment, which is a fault line that lies along the southern edge of the hills. This escarpment makes the part an attractive location for rock climbers and hikers, offering a beautiful view of the relatively flat fields below, which extend to the Ottawa River.

The above two images were created for my LIDAR flood modeling graduate research project. The first image is before the flood scenario; featuring a color shaded relief perspective view pointing south east from the Northumberland Strait landwards across the Pointe Du Chene wharf. The second image is of the same color shaded relief perspective view but features a 2.55 m flood level super imposed on top of it.
The 2.55 m flood level was an actual recorded storm surge water level that effected this area during a winter storm on January 2001. The two images below show the same flood level and area but from an overhead aerial view. The first image is with an orthophoto and the second image is with the color shaded relief.
The screen grab above was captured during the process of creating a color shaded relief model of Irvine, California. It was created in one of many demos I gave to clients while working for PCI Geomatics and was also used in the following tutorial that I created for the PCI geomatics website.
PCI Geomatics is a world leading developer of image centric geomatics software solutions. The PCI Geomatics flagship software, Geomatica, meets the growing demands of the remote sensing, GIS, cartography, and photogrammetry worlds. PCI Geomatics has long been recognized for offering high-value geomatics software solutions, advanced algorithms, excellent customer assistance, and product support for the widest range of spatial data formats in the industry.
The two images above are of a portion of the small town of Shediac, New Brunswick. Each one is of the same spatial extent, however the one on the left is of an aerial photo of the town (1999) while the one on the right is a color shaded relief model created from high resolution LIDAR data (2003) using PCI Geomatica software. The LIDAR digital surface model (DSM) was part of a LIDAR flood modeling graduate research project.
Shediac is a small town located in eastern New Brunswick approximately 20 kilometers north of Moncton. The town calls itself the “Lobster Capital of the World”, hosts an annual lobster festival every July, and the world’s largest lobster sculpture is situated at the main entrance to town.
The two images above represent artificial 3D perspective views from different points of origin featuring color shaded relief models that were created from high resolution LIDAR digital surface models as part of a LIDAR flood modeling graduate research project. The image on the left highlights a highway overpass while the image on the right features a residential area with a large school and a church easily detectable in the LIDAR all hits data set. Bouctouche is a small town located in eastern New Brunswick approximately 40 kilometers north of Moncton where the Bouctouche River meets the Northumberland Strait. It was an important aspect of the research study due to the extreme storm surge flooding that the region experiences every winter.
