The excel file was opened in ArcMap using display X, Y data tool and subsequently converted to shapefile format. The rectified points were converted to KML file using the conversion tool in ArcGIS and exported to Google earth for validation. The buildings were digitized from the downloaded Google earth image using ArcGIS 10.2.1. Shapefiles for the facilities were created in ArcCatalogue. Feature datasets were created in the geodatabase while multiple feature classes digitized from the google earth were imported into the created featured datasets. The 2D facility map was produced by digitizing all the facilities out as features from the Google earth image downloaded using Google downloader. 3D topographic maps of the study areas were created from the point data gotten from field-work and also from the downloaded SRTM DEM image downloaded from USGS, Figure 5 shows the 2D Topographic map generated from the point data gotten from the field using Total station while Figure 6 shows the 3D topographic map generated using the same data source. This study has demonstrated a capability of GIS in facility mapping with different visualizations techniques i.e. 2D and 3D visualization, Figure 2 shows the generated 2D map while Figure 4(a) and Figure 4(b) show cross-sections of the generated 3D map of the campus.
“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. In their work “Development of a Blunder Detection Approach for Automated Point Matching during Vector to Image Data Integration” also used weighted affine transformation to filter point matches during automated integration of vector roads with images. 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 3D model of the campus was produced by exporting all the features created in ArcMap to ArcScene for extrusion, the extruded features were made to float on the 3D topography map created through interpolation using Kriging method.
Figure 2. Showing the 2D facility map of the study area. Figure 3. Showing the old 2D map of the study area. 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. The 3D visualization gives the study area a near real life view. 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 created DEM was also added to ArcScene, The height of the buildings gotten from the field were added to the already created height field in the attribute table of each of the facility shapefile in ArcMap. The shapefile was added as layer. The X, Y and Z data gotten from the field were added to ArcMap.
This contains methods and procedures followed in data acquisition, processing and manipulation of data obtained from the field and also from secondary sources in order to achieve the aim of the research. When obtaining a temporary disabled person parking permit by mail, customers will be required to remit the fee payment in the form of a check or a money order. In order to be able to use disabled person's parking spaces and facilities, you must have handicapped license plates, a placard, motorcycle stickers, or an expedited service permit. You must either be the passenger or driver of vehicle for your handicap placard or license plate to be valid. A completed Application for Persons with Disabilities Parking Placard and/or License Plate (Form VTR-214), including medical certification. Dv license and the handicap application form that you have access public records request? Were made to float on DEM to have a true land representation. Extrusion incorporates the height of these features in their representation to give them 3D look. 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.
