Desperate Migrants Fight Over Water On Lesbos During Day Of Protests

ArcScene was launched and all the shapefiles were added, from the table of content each shapefile was right clicked on to access the property dialog box, from the property dialog box the shapefiles were extruded to give them 3D look and were made to float on the DEM to have a full 3D visualization. The two DEM images were called up in ArcScene of ArcGIS 10.2.1. Were extruded from the property to give it a 3D look.2.1 and were extruded from the property to give it a 3D look. The buildings were digitized from the downloaded Google earth image using ArcGIS 10.2.1. Shapefiles for the facilities were created in ArcCatalogue. The road network, buildings are extracted using polyline and polygon respectively while street lights and trees are represented by point data for 3D map production the generated 2D map is shown in Figure 2, Figure 3 shows the old 2D CAD map of the campus. 3D topographic modelled (Figure 6) from the field work because it looks more realistic and accurate, the 2D features extracted from Google Earth image was draped on the 3D topography created and extruded using the height value of the buildings gotten from the field work.

The NigeriaSat-1 and Ortho-rectified Quick-Bird images, land-use master plan and topographic map were used to generate datasets for facilities mapping and management of Abuja Federal Capital City, Phase 1. The following datasets were derived: digital road network, DTM, Tourism map, Urban and Cadastral development maps, and many more for the National Geospatial Data Infrastructure, although we extracted the facilities features from satellite image too, we relied more on the data collected from the field as a means of ground-truthing the digitized features but more importantly to generate the study area 3D topography. The transformation is applied to a local area of match points to detect probable blunders. In general, an affine transformation is a composition of rotations, translations, dilations (scales), and shears (skews). “The Accuracy of GIS Tools for Transforming Assumed Total Station Surveys to Real World Coordinates” used the transformation tools built in ArcGIS (e.g. spatial adjustment tool and georeferencing tool), to transform un-projected total station precise observations into projected real world coordinates these tools use affine transformation. All the facilities were geo-located with the aid of total station and imported into ArcGIS 10.2, the facilities were also digitized from the Google earth image downloaded for the study area.

ArcScene 10.2 software was used, finally Bello E. used assumed building heights but we used height gotten from the field using Robotic Reflector-less Total Station to get the heights. The 3D image was done ArcScene using the created DEM, The created DEM was added to ArcScene and extruded with the heights gotten on the field. Kriging interpolation technique was used to create the Digital Elevation Model (DEM). Figure 6. Showing 3D DEM (Digital Elevation Model) of the study area (derived from the field data). The importance of the data obtained from this project cannot be overemphasized, because firstly, in order to tap the resources within the area, we must have an accurate knowledge of the area. The 2D and 3D model carried out in this project identified numerous cultural and natural ground features, which include the following: Culture: roads, buildings, power transmission lines; Water: lakes, rivers, streams, swamps; Relief: slopes, depressions; Vegetation: trees cleared land, place names, water feature names, highway names. “3D Cartographic Model And Animation of As-built Educational Land-use of UNIBEN, Nigeria” he validated positional accuracy validation of UNIBEN facility map using Google Earth viewer, the KML (Keyhole Mark-up Language) converted geovisualized data fell in their appropriate locations on Google Earth, thus validating reliability and the positional accuracy of the modeled 3D dataset for further use, for this project the same thing was done (Figure 1), but we went a step further to validate the geometric accuracy of the shapefiles, topology rules in ArcGIS was used to modeled the shapefile relationship accurately.

Erinjogunola, B.A. (2017) Facility Mapping of University of Lagos. Proceedings of Technical Session NIS AGM Edo, University of Lagos, Lagos. The already available facility map only gives a simple 2D visualization and analysis of the university features, this study went from 2D to 3D spatial model which provides the 3 Dimensional model of an area for an interactive and simplified view and study, which is better for easy and better decision making. 4.

This system will provide students, academic and administrative staff and other exterior users the necessary information about the location of the campus facilities. This will help to make useful decisions. Plus, the above listed medical professionals can also help out if your disability is temporary - these temporary placards are valid for up to six months.
