RESUMO:

The geographical spatial of organisms' behavioral interactions to ecological niche spatially structured (ecological background) provides a 'living' point of contact between Ecology and Evolution. The production of cartographic bases promoted by multidisciplinary interface between Ecology, Behavior & GIS, are motivating, opportune and challenging scenario. For Primatology, the challenges of the products derived from that interface are mostly linked to the trade-offs between data accuracy and field studies restrictions. In this view, it is demanded quality certification metrics formalizing indicators of potential discrepancies of landscape structure data (imaging products) and landscape function (animal positioning) capable of compromising ecological and behavioral patterns with spatial dependence. In order to meet these demands, this Thesis aims to promote to Primatology tools of accuracy assessment and quality cartographic databases derived from remote imaging and GNSS positioning. To achieve the objectives were developed: 1. Theoretical Review with integrative approach to the body of the Thesis; 2. Evaluation of geometric correction models for high spatial resolution remote sensing images; 3. Evaluation of bias at GNSS positioning methods in forested areas, and 4. Evaluation of cartographic scale magnitude by modeled cartography products. The results of geometric correction modeling of satellite imagesshowed that antagonic scenarios (Google Maps without geometric corrections - optimistic scenario 1 and Geoeye sensor with robust ortoretifitcation methodsconservative scenario 1) are statistically equivalent (Turkey HSD: p = 0.95) and feasibility at the same work scale: 1./25,000 B-class (PEC-PCD95%) which allows working within error limited between 7.5 to 12.5 m. The GNSS positioning metrics in forested areas assessment showed three different patterns: 1. Horizontal accuracy independent of methodological complexity; 2. RTK method ineffective; 3. Vertical Accuracy dependent on carrier waves. It was also observed that the positioning methods C / A code, autonomous, GPS, instant (optimistic scenario 2) and post-processing carrier waves (L1 and L2) GNSS (GPS and GLONASS), and modeling of mitigating the effects of multi path (Floodlight technology - Trimble®) withing acquisition times of up to 15’ (conservative scenario 2) have the same cartographic scale in planimetric axis: 1 / 25,000 B-class (PEC-PCD95%). It is observed that the quality of cartographic databases derived from remote imaging sensors is dependent on the quality control data (DEMs: spatial resolution, accuracy; GCPs: number, accuracy, spatial distribution), while the quality of positioning by GNSS in forested areas is a nebulous issue due determination of control data. The results of this thesis demonstrate feasibility of geometric modeling for high spatial resolution remote sensors at low cost and equivalence of quality positioning data for low complexity GNSS in forested area in planimetric axis. The thesis deepening discussions about relations costs / benefits of the presented instrumental solutions and potential applications for Ecology, Behavior & GIS interface. Finally, it is concluded that this Thesis contributes the following perspectives: i. Presents in depth and adjusted to the profile of readers of Ecology, Behavior and Primatology problematic as the absence of formal instruments of management of cartographic databases and data quality indicators in Ecology, Behavior & GIS interface as well as state of the art of this instrumental ensemble; ii. Formalizes and evaluates instrumental models of generation and correction of cartographic bases of imaging sensors high spatial resolution and positioning GNSS in forested areas; iii. Respond to trade-offs between quality and feasibility of cartographic products in Primatology through optimal cartographic scale formalized by the indicators of the magnitude of errors.
