Geospatial Resource Analysis

Analyzing spatial components as data,
to be mapped as results.

D&D Larix, LLC, provides a highly customized service for you. Our approach to a well-designed product implies our awareness of your professional needs. We fill the gaps by answering questions not even asked. We strive to broaden the interpretation of the GIS tool beyond creating a mere visual representation of data layers in the shape of physical or digital maps. We extend your knowledge and professional expertise by extrapolating existing fixed parameters of today's data into more flexible patterns of its interpretation for future prognostication needs. D&D Larix, LLC, operates a full service Geospatial Analysis Center (GIS Lab) known as Geospatial Resource Analysis. Our services include a wide array of custom map printing, features analysis, multi-spectral image analysis, satellite imagery dissection, linear and non-linear multi-attribute regression analysis, Kriging, variography, geo-statistics determination, and more!

We complete vector and raster data analysis, commercial map printing and special job map generation to best suit your needs. In addition, we will integrate GPS data (complete data dictionary management, post collection differential correction) into your GIS project complete with feature attributes. We will then perform full evaluations of the data to generate its visual, temporal, and spatial representations. Geospatial Resource Analysis offers you a Geographic Information Systems Laboratory capable of not just mapping attributes, but full analysis of a broad range of geographic, social, biological, and physical attributes, designed to facilitate planning sessions and management decisions.

We Analyze what others did not even know was a question

Digital elevation models have been available since GIS was first applied to cartography and mapping centuries ago. The digital-age really stepped into natural resources management along with the introduction of Personal Computers (PCs) in the early-1990’s. From that pivot point, data storage and rapid accessibility gave the new technological advancement a super-charge giving value to information processing and storage of HUGE amounts of data.

“Raster is Faster, but Vector is more-correcter” became a slang used in spatial analysis groups, insinuating that raster data with its 90 meter resolution was somehow faster to analyze than the polygons, lines, and points of the vector world. Today, those original 90 meter DEM databases have been replaced federally, with the USGS, with 30 meter, and now 10 meter resolution DEM models of most of the USA. Some areas have been assessed with¬† Light Detection And Ranging (LiDAR) flights. Generally collected by fixed wing aircraft (also airborne laser scanning), the images can collect geo-positioned elevation points of the ground and tree height characteristics from the ground to tree tops.

These high definition 1 meter DEM arrays are 8,000 times more dense than their 90 meter predecessors. That density takes storage space and computational power to analyze. The data generated are truly powerful for the analyst to integrate into the cadre of natural resource attributes.

Combining these DEM data with other data gives meaning to why these efforts are made. Watching the adjoining panel, the viewer will watch a series of analysis steps to convert the raw LiDAR field into a hillshade image, refine it to reveal heightened contrast, then to normalize the scene as an unsupervised road width algorithm is applied. Geospatial Resource Analysis has developed these techniques and written the code to reveal broad areas where road widths are discovered, road center-lines are linked, and terrain conditions are investigated.

LiDAR DEM data are used to predict where stream networks are located across the landscape, from mountain peak to ocean pour-point. The 1m DEM data provide high resolution to the central location of the channel, but further investigations reveal stream width at full-channel, stream migration zones, and flood plains. We use these data to combine with the LANDSAT 8 OLS multispectral satellite imagery scenes, soil type data, and vegetative associations to discover more than ever before.

This is what we do.

Custom Mapping

Custom mapping, in a sense, is a nonsensical phrase because all maps are a custom creation. The unique components we provide come in the form of seeking and locating unique features to explain environmental interactions of the physical site characteristics being considered.
