GIS-36: REMOTE SENSING APPLICATIONS IN RESOURCE INVENTORIES (IUFRO)

Order No:

GIS-36

Total Length:

275 minutes



Replacing Aerial Photo Interpretation in Resource Inventories with Integrated Airborne Digital Data and GIS

Reference No:

GIS 36-1

We are moving towards integrated GIS, where database photographs represent only one layer of information. Geometrically registered photographs (orthophotos) combined with multispectral imagery, 3-D visualization of clearcuts or regeneration of forest, are currently being used operationally.

Airborne Linear Array Imagers for Forestry Applications

Reference No:

GIS 36-3

Concensus results of The International Forum on Airborne Multispectral Scanning for Forestry and Topographic and Cartographic Mapping.

Discussed are Systems Requirements and Specifications for airborne imagery for forest applications - number of bands, spatial resolution, swath width, hardware, software, etc. Applicable for forest inventory updating, forest mapping and forest damage assessment. Specifications are given for the various types of applications. Costs are compared to traditional techniques.

Influence of Forest Stand Parameters on Vegetation Indices used for Coniferous Forest Damage Assessments

Reference No:

GIS 36-4

The aim of this critical approach project is to quantify the influence from forest stand parameters on 6 vegetation indices, relative to stand parameters, used in assessment of forest decline. The study area was 1300 hectares in Sweden, using a combination of thematic mapper and field work.

Effect of Polarization on Radar Backscatter in Relation to Slash Pine Stand Biomass Using SAR Aircraft and SIR-B Data

Reference No:

GIS 36-5

The presentation examines four different polarization techniques on slash pine plantations. Radar backscatter and forest stand parameters are examined in terms of correlation. The study area was NE Baker County, Florida, using TM and SIR-B data. The purpose of the experiment was to estimate biomass from radar backscatter. The model was developed from 35 stands and verified from another 35 stands.

Feature Extraction from Landsat TM Pixels

Reference No:

GIS 36-6

It has been established that the basic spectral characteristics of shrub-dominated rangelands are complex and not well-known. This presentation describes attempts to measure certain kinds of desert vegetation attributes using remote sensing technology. The work is being done with thematic mapper data to see if information from individual pixels can be extracted to help understand inherent spectral characteristics of the ground, vegetation and soil. The procedure used was pixel modeling - whereby the spectral mixture inherent in an individual pixel is separated into various known components. The presentation describes how pixel component modeling is used to "estimate" the important range variables.

Background Effects on Reflectance and Derivatives using Airborne Imaging Data

Reference No:

GIS 36-7

Measuring crown closure may not be a simple task, particularly in sparse canopies. The reflectance background component is of sufficient importance that it must be taken into account in data analysis. This presentation summarizes the results of a study of background components' effects on reflectance and derivatives spectra, as it relates to crown closure.
