Esri shapefile extension for babacad

QGIS free to download?Yes, QGIS is free to download from the official website, QGIS.org. It is an open-source GIS software that provides powerful capabilities for analyzing and visualizing geospatial data.Can you export from Google Earth as shapefile?To export data from Google Earth as a shapefile, you will need to utilize ArcToolbox in ArcGIS software. Import the KML files created in Google Earth and Google Maps, then use the conversion tools to export them as a shapefile in the same coordinate system as your map.Is there a free ArcGIS viewer?Yes, ArcGIS Explorer is a free application provided by Esri that allows users to view and share geographic information. It provides various tools and functionalities for working with spatial data.Can you download GIS data from Google Earth?Google Earth Pro allows users to upload and download geospatial data in its native file format, KML. It also offers access to high-resolution satellite imagery and historical images, making it a valuable tool for GIS data exploration.What files make up a shapefile?A shapefile consists of three essential components:1. The main file with a .shp extension, which contains the feature geometry.2. The index file with a .shx extension, which stores the index of the feature geometry for faster access and querying.3. The dBASE table with a .dbf extension, which stores the attribute information of the features.Can Excel open a shapefile?Excel cannot open a shapefile directly since shapefiles are spatial data files used by Geographic Information System (GIS) software. However, you can use Excel to open and edit

Format CSV - Comma-Separated Values 🔸 File extension .shp .csv 🔸 MIME type application/x-sh text/csv 🔸 Developed by Esri Informational RFC 🔸 Type of format multi-platform, serial data streams 🔸 Description The shapefile format (SHP) is a geospatial vector data format for geographic information system (GIS) software. Esri developed and regulated it as a mostly open specification for data interoperability among Esri and other GIS software products. The shapefile format can spatially describe vector features: points, lines, and polygons, representing, for example, water wells, rivers, and lakes. In addition, each item usually has attributes that describe it, such as name or temperature. In computing, a comma-separated values (CSV) file stores tabular data (numbers and text) in plain text. Each line of the file is a data record. Each record consists of one or more fields, separated by commas. The comma as a field separator is the source of the name for this file format. 🔸 Technical details The CSV file format is not standardized. The basic idea of separating fields with a comma is clear, but that idea gets complicated when the field data may also contain commas or even embedded line-breaks. CSV implementations may not handle such field data or use quotation marks to surround the field. 🔸 File conversion SHP conversion CSV conversion 🔸 Associated programs ArcGIS, MapViewer, Merkaartor Microsoft Excel, LibreOffice Calc 🔸 Wiki Popular document conversions

Developing BabaCAD Extension Modules Currently (2014), there is no free CAD software with customization option, with exception of BabaCAD. Developers can extend BabaCAD with runtime extension modules (BEM). BEM modules are simply dll's that BabaCAD loads in runtime and executes custom commands and functions. To start programming these Add-On modules for BabaCAD, you need to have Microsoft Visual Studio 2010 and also you need some knowledge of c++. I will here give an example of custom application (BabaCAD BEM Add-On module) that allows you to draw slope lines, one of the important features in civil design. We will define two additional (custom) commands: SLOPE and SLOPESET. Also to help other users to start using add-on easy, we will also create new toolbar with two icons for new commands. 1. Start Visual Studio and create a new MFC DLL project "CivilTools" in c++ templates. 2. Open Project properties and change output extension from .dll to .bem 3. Add declarations of Slope, SlopeSet, CivilTools functions and also default entry point function for BabaCAD extension (file CivilTools.h): #include "resource.h" // main symbols extern "C" { BOOL __declspec(dllexport) BabaCADExtEntryPoint(TCHAR &defaultCmdSymbol, TCHAR &getVarSymbol); BOOL __declspec(dllexport) Slope(int &CmdSeq); BOOL __declspec(dllexport) SlopeSet(int &CmdSeq); BOOL __declspec(dllexport) CivilTools(int &CmdSeq); } 4. Open CivilTools.cpp, add BabaCAD extension header and lib, add entry-point function and command functions: #include "stdafx.h" #include "\Program Files (x86)\BabaCAD\BabaCAD\API\Inc\BabaCADExtensions.h" #include "CivilTools.h" #import "\Program Files (x86)\BabaCAD\BabaCAD\API\Lib\BabaCAD.lib" no_namespace BOOL BabaCADExtEntryPoint(TCHAR &defaultCmdSymbol, TCHAR &getVarSymbol) { AFX_MANAGE_STATE(AfxGetStaticModuleState()); AddCommand(_T("Slope"),L"",_T("Terrain slope lines"),_T("CivilTools.bem"), m_hInstDLL, ID_SLOPE); AddCommand(_T("SlopeSet"),L"",_T("Configure slope lines"),_T("CivilTools.bem"),m_hInstDLL ,ID_SLOPESET); AddCommand(_T("CivilTools"),L"",_T("Civil Tools"),_T("CivilTools.bem"),m_hInstDLL); return TRUE; }
