Preparation of the Digital Elevation Model for Orthophoto Cr Production
The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, Volume XLI-B3, 2016 XXIII ISPRS Congress, 12–19 July 2016, Prague, Czech Republic PREPARATION OF THE DIGITAL ELEVATION MODEL FOR ORTHOPHOTO CR PRODUCTION Z. Švec a, K. Pavelkaa a Czech Technical University in Prague, Faculty of Civil Engineering, Thákurova 7, Prague 6, 166 29, Czech Republic - [email protected] Commission III, WG III/1 KEY WORDS: Airborne Laser Scanning, Digital Elevation Model, Orthorectification, Surface Modelling, True Orthophoto ABSTRACT: The Orthophoto CR is produced in co-operation with the Land Survey Office and the Military Geographical and Hydrometeorological Office. The product serves to ensure a defence of the state, integrated crisis management, civilian tasks in support of the state administration and the local self-government of the Czech Republic as well. It covers the whole area of the Republic and for ensuring its up-to-datedness is reproduced in the biennial period. As the project is countrywide, it keeps the project within the same parameters in urban and rural areas as well. Due to economic reasons it can´t be produced as a true ortophoto because it requires large side and forward overlaps of the aerial photographs and a preparation of the digital surface model instead of the digital terrain model. Use of DTM without some objects of DSM for orthogonalization purposes cause undesirable image deformations in the Orthophoto. There are a few data sets available for forming a suitable elevation model. The principal source should represent DTMs made from data acquired by the airborne laser scanning of the entire area of the Czech Republic that was carried out in the years 2009-2013, the DMR4G in the grid form and the DMR5G in TIN form respectively. -

Digital Orthophoto Generation with Aerial Photos and Satellite Images and Analyzing of Factors Which Affect Accuracy
Digital Orthophoto Generation with Aerial Photos and Satellite Images and Analyzing of Factors which Affect Accuracy Eminnur AYHAN, Özlem ERDEN, Gülçin ATAY and Esra TUNÇ, Turkey Key words: Digital orthophoto, accuracy, DEM, land characteristic, satellite image, aerial photograph SUMMARY With the development of technology Digital photogrammetry has been started to be used widely in almost all area about mapping. Especially digital orthophotos which are a photogrammetric products, are being used common by lots of private sectors because of theirs easy interpretability. This has increased the demand on maps and has led to the need of researching on about accuracies. The resolution and the scale of the used aerial photos or satellite images, the quality and the scale of the DEM (Digital Elevation Model) and land topography are some of the factors that affect the accuracy of the orthophotos. The affects of the DEM and land topography on orthophoto accuracy have been investigated in this study. Firstly the affects of DEM on orthophoto maps which are produced either by aerial photos or satellite images has been investigated. Secondly, to determine the affect of topography on the process, some scanned aerial photos and the panchromatic (PAN) band of IKONOS satellite have been used. These scanned aerial photos are belong to the different regions in Turkey like Trabzon, Aydın, Tekirdağ ve Siirt, with different scales and resolutions (14μm-21μm) and they also represent different topography properties (rough, flat). Then the orthophoto maps, generated -

Digital Orthophoto Generation with Aerial Photographs
E-ISSN 2281-4612 Academic Journal of Interdisciplinary Studies Vol 3 No 7 ISSN 2281-3993 MCSER Publishing, Rome-Italy November2014 Digital Orthophoto Generation with Aerial Photographs 1Lawali Rabiu 2Dauda Waziri A. 1&2 Federal Polytechnic Damaturu, Yobe State, Nigeria Email: [email protected] Doi:10.5901/ajis.2014.v3n7p133 Abstract Orthophoto process transforms a vertical aerial photograph in to the equivalent of traditional map. Yet it retains the advantages of a photograph-virtually displaying actual cultural and land features and the built environment rather than representing those features using symbols and lines. With the development of technology, Digital photogrammetry has started to be used widely in almost all areas about mapping. Especially digital orthophotos which are a photogrammetric products, are being used by lots of private sectors because of theirs easy interpretability. Several photogrammetric software which can be use to generate orthophotos are Leica Photogrammetric System (LPS), PCI Geomatica, Topcon pi 3000, Image Master, Erdas Imagine, VirtuoZo and others. In this study photogrammetric data from aerial photographs was used to generate orthophoto using erdas imagine software. The processing procedure of the system is described in detail. Sets of measurements (length and width) of selected buildings were obtained. The results obtained from this software are compared with ground survey measurement. The results showed that an accuracy of sub-meter of ±0.406m could be obtained from orthophoto generated using erdas imagine software. Conclusion is drawn concerning the suitability of the software for use in orthophoto generation. Future research is recommended based on two or more photogrammetric systems to comprise both side overlap and end overlap. -
A Statistical Examination of Image Stitching Software Packages for Use with Unmanned Aerial Systems
A Statistical Examination of Image Stitching Software Packages For Use With Unmanned Aerial Systems John W. Gross and Benjamin W. Heumann Abstract There is growing demand for the collection of ultra-high spatial orthomosaic. This issue is typically addressed using aerial resolution imagery, such as is collected using unmanned aerial photogrammetric techniques. systems (UAS). Traditional methods of aerial photogrammetry One of the more conventional ways to handle the creation are often difficult or time consuming to utilize due to the lack of orthomosaics in aerial photogrammetry is through the of sufficiently accurate ancillary information. The goal of this use of automatic aerial triangulation (AAT) and bundle block study was to compare geometric accuracy, visual quality, and adjustment (BBA). In this method, software is able to utilize price of three commonly available mosaicking software pack- interior orientation (IO) information provided by the camera, a ages which offer a highly automated alternative to traditional global positioning system (GPS), and an inertial measurement methods: Photoscan Pro, Pix4D Pro Mapper, and Microsoft Im- unit (IMU) to match individual images together then adjust age Composite Editor (ICE).

Assessing Horizontal Positional Accuracy of Google Earth Imagery in the City of Montreal, Canada
GEODESY AND CARTOGRAPHY ISSN 2029-6991 / eISSN 2029-7009 2017 VOLUME 43(2): 56–65 https://doi.org/10.3846/20296991.2017.1330767 UDK 528.931.1 ASSESSING HORIZONTAL POSITIONAL ACCURACY OF GOOGLE EARTH IMAGERY IN THE CITY OF MONTREAL, CANADA Mohammad Ali GOUDARZI, René Jr. LANDRY École de technologie supérieure (ÉTS), Laboratory of Space technologies, Embedded System, Navigation and Avionics (LASSENA), 1100 rue Notre Dame Ouest, Montreal (QC), H3C 1K3, Canada E-mail: [email protected] (corresponding author) Received 06 February 2017; accepted 10 May 2017 Abstract. The horizontal positional accuracy of Google Earth is assessed in the city of Montreal, Canada, using the precise coordinates of ten GPS points spatially distributed all over the city. The results show that the positional accuracy varies in the study area between ~0.1 m in the south to ~2.7 m in the north. Further- more, two methods are developed for correcting the observed positional errors: (a) using a set of transfor- mation parameters between true coordinates of the geodetic points and their coordinates in Google Earth, and by (b) interpolating the misfit vectors at the geodetic points. The former method reduces the overall accuracy to ~67 cm RMSE, whereas the latter one practically removes all the distortion (RMSE = 1 cm). Both methods can be developed for other places in the world subject to availability of appropriate control points. In addition, a displacement problem caused by the topography of the area and the viewing angle of the imaging satellite is discussed, and it is shown that the true positions can be shifted even up to several meters, as a consequence. -

Technische Universität Berlin Master Thesis Analysis of potential distribution and size of photovoltaic systems on rural rooftops A contribution to an optimized local energy storage system with a remote sensing and GIS-based approach in Swabia, Germany A thesis submitted in fulfilment of the requirements for the degree of Master of Science Environmental Planning by Ana González Quintairos Matriculation number: 349833 First Supervisor: Prof. Dr. Kleinschmit Second Supervisor: Dr. Jochen Bühler Faculty VI Planning-Building-Environment Geoinformation in Enviromental Planning January 2015 In cooperation with Reiner Lemoine Institut gGmbH Abstract Abstract This work studies the distribution of photovoltaic systems in rural areas. The aim of the study is to create a method which predicts the size and location of future photovoltaic systems on rooftops. Only very few authors have also attempted to use high-resolution images to quantify the suitable rooftop surface per building and the appropriated loca- tion of the panels and none of them have addressed the particular building distribution and typology of rural communities. Addressing rural areas has a tremendous importance in Germany where highest PV potential in Germany is expected. The methodology uses as inputs high-resolution aerial imagery, GIS building footprint from the Land-register map and the Bavarian database of photovoltaic systems. The method has been applied to the village of Freihalden (Bavaria) using two different type of images: official orthophotos from the Bavarian Land-survey Office and Google Earth™ orthophotos and the results on rooftop suitable area and on rooftop potential for PV have been compared with each other. The study area is located in Freihalden, Bavaria.
