What does DOQ mean in MATHEMATICS
Digital Orthographic Quadrangle, or DOQ, is a type of digital imagery data format that is used to represent aerial and satellite images. It is a vector-based image composed of a mosaic of standardized 1 km by 1 km quadrangle tiles which contain the data regarding the topography, land cover, and other features of an area.

Essential Questions and Answers on Digital Orthographic Quadrangle in "SCIENCE»MATH"
What are the uses of DOQ?
DOQs can be used for many different types of applications such as mapmaking, land cover classification, construction planning, geographic information systems (GIS), habitat management, urban planning and development, remote sensing analysis, and more.
What type of data does a DOQ contain?
A DOQ contains data about the topography and land cover in an area such as roads and buildings, elevation data, vegetation indices, bathymetric depth contours for bodies of water and rivers, digital terrain models (DTMs), vegetation classifications (land use/land cover categories), hydrologic features (e.g., wetlands), cultural features (e.g., monuments), aerial photography images and more.
What format is a DOQ in?
A Digital Orthographic Quadrangle is usually stored in TIFF image file format in units such as kilometers or meters per pixel. It can also be compressed into formats such as ECW or JPEG2000 for smaller file sizes.
How can I access a Digital Orthographic Quadrangle?
Many government organizations provide access to DOQs through their websites. Other sources include private providers such as Geospatial Data Services Incorporated (GDSA). You may need to purchase annual subscriptions in order to access certain DOQs from certain providers.
Is there any software required to view Digital Orthographic Quadrangles?
Yes - you will need GIS software that supports viewing vector-based imagery such as ESRI ArcMap or QGIS in order to open and interact with these digital orthographic quads.
Final Words:
Digital Orthographic Quads are an important tool for viewing detailed aerial imagery over large areas. The entirety of an area's terrain can be accessed using this technology without having to physically travel there due to its ability to store vector-based imagery composed of standardized 1 km by 1 km quadrangle tiles containing data about topography and land cover information including roads & buildings, elevation detail, vegetation indices & classification etc. With suitable GIS software like ESRI ArcMap or QGIS these quads can be viewed quickly with convenience allowing users to save time & money while efficiently obtaining correct geospatial information from the comfort of their own homes.
