Larson Back to Table of Contents ------------------------------------------------------------ INTRODUCTION This digitally compiled map includes geology, oil and gas field centerpoints, geologic provinces, and major faults of Iran with some of these components extended into geographically adjacent areas. This digital compilation is an interim product of the U.S. Geological Survey's World Energy Project (WEP) and part of a series on CD-ROM. The goal of the WEP is to assess the undiscovered, technically recoverable oil and gas resources of the world and report the result of this assessment in the year 2000. For data management purposes, the world was divided into eight energy regions corresponding approximately to the economic regions of the world as defined by the U.S. Department of State. Each world energy region was then further divided into geologic provinces on the basis of natural geologic entities and may include a dominant geologic structural element or a number of contiguous elements. Some provinces contain multiple, genetically related basins. Geologic province boundaries for Iran were delineated using data from different geologic maps, publications, and other tectonic and geographic data. Each province was assigned a unique number; the first digit is the region number. An attempt was made to number the provinces in geographical order or groups (see Pollastro and others, 1998). The list of provinces sorted by number is shown to the right of the map. Centerpoints of oil and gas fields are shown and were plotted with permission from Petroconsultants International Data Corporation, 1996 worldwide oil and gas field database. Allocation of field data to geologic provinces provided a ranking of the provinces by total known petroleum volume (see Klett and others, 1997). The WEP further characterizes the geologic provinces by petroleum system and assessment units in order to assess the undiscovered petroleum volume. Specific details of map and data sources, and the procedure used in the compilation of this geologic map of Iran are given in the metadata files and described briefly in the text below. Stratigraphic subdivisions of Phanerozoic rocks were combined to simplify the geology and maintain consistency with other maps in this series. Precambrian rocks are undivided. This map was compiled using Environmental Systems Research Institute, Inc. (ESRI) ARC/INFO software. Political boundaries and cartographic representations are used, with permission, from ESRI's ArcWorld 1:3M digital coverages, have no political significance, and are displayed for general reference only. Version History: Version 1.0 : October 1999 Back to Table of Contents ------------------------------------------------------------ DATA PROCESSING STEPS This map has been digitally compiled and abstracted from The Geological Map of Iran, (1985) Compiled by A. Haghipour and A. Aghanabati, Ministry of Mines and Metals, Geological Survey of Iran, Scale 1:2,500,000. The projection information written on the original map is ".. adjusted from Polyconic Projection of International 1:1000000 Map of the Earth". Because such projection is not directly supported by ESRI's ARC/INFO software, it was necessary to georeference the map to the one of known projections. This was done as follows: 1. The latitude/longitude grid with cell size 2 * 2 degrees was projected to Lambert Conformal Conic projection and then used to create ARC/INFO point coverage. That point coverage was used to create "to - from" links by ARC/INFO CONTROLPOINTS program. 2. A gray scale scanned image of the original paper map was transformed to Lambert Conformal Conic projection by ARC/INFO GRIDWARP program (polynomial of the second order) using the "to - from" links created by CONTROLPOINTS program. 3. Geologic polygon boundaries from source map were initially transferred to mylar and then scanned to produce binary image. 4. Binary image from step 3 with geologic boundaries was vectorized by ARC/INFO GRIDLINE utility and then supplemented by hands-on digitization. 5. Polygon boundaries and geologic attributing of the ARC/INFO coverage from step 4 were verified and corrected by using gray scale image from step 2 as a background. 6. A series of piecewise "rubbersheet" transformations was applied to the final ARC/INFO coverage. The ARC/INFO coverages that were used for transformation were ESRI's ArcWorld 1:3M GIS cartographic layers (RIV3M, CTRY3M). Overall RMS error of that transformation is equal to 1,500 meters (0.6 mm on original paper map). back to Contents ------------------------------------------------------------ SDTS EXPORT DATA The Spatial Data Transfer Standard (SDTS) is a data exchange format for transferring different databases between disimilar computing systems, preserving meaning and minimizing the amount of external information needed to describe the data. SDTS is documented in FIPS publication 173 available from the U.S. Department of Commerce. All SDTS transfers adhere to the following naming conventions. The files in a transfer all begin with the same four character prefix followed by a valid module name. In most cases the module name is a four character mnemonic (see table on SDTS modules). For spatial objects, it is normally one or two characters followed by a sequence number, nnn, or nn respectively. The transfer file names may contain both alpha and numeric characters. All characters are in uppercase. There are three SDTS Export Modules in this CD-ROM corresponding to three main Arc/Info coverages (data layers): 1. All the files with prefix GEO- surface geology. 2. All the files with prefix FLT - faults. 3. All the files with prefix PRV - USGS geologic Provinces. General information on these data can be obtain in README file in SDTS_EXP directory of this CD-ROM. back to Contents ------------------------------------------------------------ CD Organization CD root 1st 2nd 3rd Description of97470g ACROREAD Installable versions of Adobe Acrobat Reader ACROREAD.HTM MAC UNIX Contains Tar and compressed files for installation on seven Unix platforms WIN Contains installation executables for five Intel based OS systems apple Introductory information on the use of the CD in a Mac text format ARCEXPLR Installable version of ESRI's ArcExplorer v1.1 IRAN Prime directory for Iranian GIS data ARC_COVR ESRI Arc coverages in a Lambert Conformal Conic projection CITY_IR Major cities CTRY_IR Reference political boundaries INFO Arc INFO directory IR_FAULT Major geologic faults IR_FLD Centerpoints of Oil and Gas fields (Petroconsultants) IR_GEO Surficial geology IR_LLF Latitude/Longitude grid with cell size 2 * 2 degree IR_PROV Geological Provinces that outline areas with common geological structures and petroleum systems OUTLINE Outer map boundary COVR_GEO ESRI Arc coverages in Geographic coordinates (decimal degrees) INFO Arc INFO directory IR_FLD_G Centerpoints of Oil and Gas fields (Petroconsultants) IR_FLT_G Major geologic faults IR_GEO_G Surficial geology IR_LLF_G Latitude/Longitude grid with cell size 2 * 2 degree IR_PROV_G Geological Provinces that outline areas with common geological structures and petroleum systems OUTLINE_G Outer map boundary EXPORT Data duplicated in formats not used for project work including Arc-EXPORT, Arc-UNGENERATE, comma delimited formats.

Back to Getting Started ------------------------------------------------------------ ESRI ArcExplorer Project ArcExplorer is developed for Windows 95/98/NT, but Macintosh computers capable of running Windows emulators such as SoftPC (TM) and VirtualPC (TM) can run ArcExplorer projects from this CD-ROM. ArcExplorer 1.1 is provided in this CD-ROM for local installation. The installation program, aeclient.exe, is found in the ARCEXPLR directory. ArcExplorer can also be obtained from ESRI's web site: An ArcExplorer tutorial in Adobe Acrobat Portable Document Format (explorer.pdf) is provided in the ARCEXPLR directory. The ArcExplorer project IR_GEO.AEP is located in the root directory. Accessing these projects is done by either double clicking on the IR_GEO.AEP icon, or by starting ArcExplorer: opening FILE, OPEN PROJECT, and selectingIR_GEO.AEP. For fastest performance, it is suggested to copy IR_GEO.AEPand the entire views30directory to your hard drive (Approximately 21 MB). The directory is designed to be self-contained and requires no other files. Back to Getting Started ------------------------------------------------------------ ESRI ArcView Project ESRI's Arcview 3.x is used to create the U.S. Geological Survey Arcview Project. Note ArcView software is not supplied on this CD-ROM. Use of the ArcView project files (.APR) requires ArcView 3.0 or greater. There are two versions of the Arcview project found on this disk. Both can be found in the directory IRAN/VIEWS30 . The first, IR_GEO.APR, can be viewed on any platform where Arcview 3.x is already installed. Some modifications to your system, explained below, are suggested. The second, IR_GEOPC.APR, can be viewed on Windows 95/98/NT platforms without any modification. For a detailed explanation of system modifications please see the INSTALL.HTM file. If the operating system is Windows 95/98/NT, access the project IR_GEOPC.APR in the directory IRAN/VIEWS30. If another operating system is used, an environmental variable, AVDATA_IR, must be defined in order to optimally access the ArcView project located in the directory IRAN/VIEWS30. For a more comprehensive discussion see the INSTALL.TXT file in the appropriate platform subdirectory of IRAN/VIEWS30. On a Macintosh platform modify the "startup" file in the Preferences folder of the System folder to include:System.SetEnvVar ("AVDATA_IR", "OF97470G") An example "startup" file, startup, can be found in the directory IRAN/VIEWS30/MAC. The text file, startup, can be dragged into the Preferences folder within the System folder. Unix users will need to define AVDATA_IR in the ".cshrc file." With a UNIX machine it is assumed that the CD-ROM drive is refered to as /cdrom. Modify the ".cshrc" file with a statement like: setenv AVDATA_IR /cdrom/OF97470G Subsequently, a logout and login or "source" the .cshrc file will set the variable AVDATA_IR. Windows 95/98 users can define AVDATA_IR in the autoexec.bat file as follows: SET AVDATA_IR =
