Abstract/Description
-
Normal color digital ortho-photos with six inch resolution were used to test the feasibility of mapping the habitat of the Florida apple snail, the exclusive food source of the Endangered Florida snail kite. Several remote sensing techniques such as unsupervised and supervised classifications are evaluated and accuracy assessed. While the overall ability to classify apple snail habitat is significant, sparse areas of emergent vegetation which are preferred foraging areas for the kite were...
Show moreNormal color digital ortho-photos with six inch resolution were used to test the feasibility of mapping the habitat of the Florida apple snail, the exclusive food source of the Endangered Florida snail kite. Several remote sensing techniques such as unsupervised and supervised classifications are evaluated and accuracy assessed. While the overall ability to classify apple snail habitat is significant, sparse areas of emergent vegetation which are preferred foraging areas for the kite were excluded by the classification and needed to be re-introduced for further analysis. The methodology can be repeated to measure change over time since the NC imagery of Grassy Waters Preserve is acquired frequently. Additionally, three spectral levels of density abundance of wetland graminoid species that denote apple snail habitat were examined for mapping potential on the imagery. A site suitability analysis using a weighed overlay tool in ArcGIS is suggested as a means to include numerous other key factors influencing habitat selection by the snail kite in a mapping project.

Abstract/Description

Knowledge of the geospatial distribution of vegetation is fundamental for resource management. The objective of this study is to investigate the possible use of airborne LIDAR (light detection and ranging) data to improve classification accuracy of high spatial resolution optical imagery and compare the ability of two classification algorithms to accurately identify and map wetland vegetation communities. In this study, high resolution imagery integrated with LIDAR data was compared jointly...
Show moreKnowledge of the geospatial distribution of vegetation is fundamental for resource management. The objective of this study is to investigate the possible use of airborne LIDAR (light detection and ranging) data to improve classification accuracy of high spatial resolution optical imagery and compare the ability of two classification algorithms to accurately identify and map wetland vegetation communities. In this study, high resolution imagery integrated with LIDAR data was compared jointly and alone; and the nearest neighbor (NN) and machine learning random forest (RF) classifiers were assessed in semi-automated geographic object-based image analysis (GEOBIA) approaches for classification accuracy of heterogeneous vegetation assemblages at Everglades National Park, FL, USA.
