Raster To Vector Conversions — A Serious Business
With rapidly increasing technologies more and more companies are searching for new ways to gain a lead in the market, raster to vector (R2V) conversion is becoming a standard of expectation. Raster to Vector conversion also known as R2V caters to the diversified fields ranging from commercial to industrial. More than 60 countries use R2V for mapping and GIS data conversion applications. Architectural, engineering, construction, electrical and house plans are all regulars of the raster to vector conversion. The raster to vector conversion can be applied to convert data or image into vector format. The advantages of raster to vector (R2V) conversion include: A vector image has no jaggedness, no loss in detail and can be printed at any resolution or any size.This vector image can be scaled up or down without any loss in quality.Also the archive of the vector artwork can be used for manuals, brochures, newspapers and a host of other areas.Raster to vector conversions enables you to convert technical drawings, maps logos and any other graphics from raster to vector formats, for easy archiving and instant access. Raster to vector (R2V) procedure can be used to process charts, drawings, maps, schemes and other similar images.Applications:Raster to vector conversion of Technical Drawings (AEC)Raster to vector conversion of House plansRaster to vector conversion of GIS (CAD)Raster to vector conversion of BlueprintsRaster to vector conversion of LogosVectorization for website applicationsVectorization for Graphic Design purposesOne of the many ways to achieve the raster to vector conversion can be recreating the vectorized output using AutoCAD (DWG, DXF), MicroStation (DGN), Adobe Illustrator (AI), CorelDraw (CDR), VectorWorks, etc.By: Rohini SoodGPS Shop
GIS Mapping Basics
Geographic Information Systems, or GIS, are systems that gather, organize and analyze data in terms of its geographical location. GIS mapping uses computer software to register data from land surveys, aerial and satellite photography, as well as a wide variety of other sources. This data is then combined and represented in map form.By layer data in geographical form, Geographic Information Systems mapping can tell us a lot about a particular location that we didn’t know before. The data input can include things like, rivers, mountains, streams, roads, gas stations, highways, bus stops, etc. Statistical data like census figures and other demographical information can also be fed into a GIS to produce different geographical analyses. The kind of data you input into a GIS depends on the type of analysis you are trying to acquire about a given location. For example, you can input a city’s crime stats onto a geographic information system and come up with a map the gives you a visual of where the areas with most crime in the city are and so forth. From this data mapping we can identify patterns and perhaps even find out their cause.The thing that GIS mapping depends on is the fact that most data sets contain some form of geographical reference. That is, a zip code, a city, country, or an address. GIS maps are dynamic, meaning they change according to what data goes into them or what data is taken out. This makes them incredibly useful in a variety of fields, and the full potential of Geographic Information Systems mapping remains yet to be seen.Until recently, GIS mapping was primarily used by governments and large corporations to analyze data pertinent to them. However, as cellphones, iPods, laptops and other mobile computer… Continue reading
GIS Aerial Maps – Discover the Many Uses
Geographic Information System or GIS is technology that offers a radically different way to produce and use the maps required to manage our communities and industries. GIS helps create intelligent super maps through which sophisticated planning and analysis can be performed at the mere touch of a button.GIS aerial maps can greatly enhance a GIS mapping project. Aerial imagery is a powerful visual aid and serves as a source of derivative information such as land cover, terrain, change detection, or vegetation.Today there are perhaps thousands of geospatial applications in use. Organizations, agencies and companies throughout the world use the technology to transform manually produced maps and associated descriptive records into digital databases. Once a tool that was affordable only to the largest organizations, geospatial systems and GIS aerial maps have become a cost effective option for even the smallest organizations.Geographic information system technology is widely used for scientific investigations, natural resource management such as forestry, agriculture, mining, oil and gas exploration, environmental impact assessment, and urban planning.GIS and GIS Aerial Maps can be used in a wide range of activities, such as: GIS base mapping, corridor mapping, land cover classification, urban development, pre and post 2D/3D seismic surveys, Environmental Impact Studies (EIS), environmental monitoring, coastal erosion studies, property and tax mapping, and flood analysis. You likely can even think of other uses for GIS not listed here, although it sounds cliche; the possibilities truly are almost endless.Some GIS projects are hindered by coordinate problems of different image and vector data layers, which are caused by one or a combination of the following: Improper orthorectification of satellite or aerial image mosaics. Poor quality GPS derived ground control points (GCPs). Improper rectification of digital source raster maps. Importation of vector data or shape files… Continue reading
