Satellite: A satellite map is a map that is created using satellite imagery. In addition, we add more local measurement units every now and then to make it more convenient. There are several different units of measurement for area, including square meters, square feet, acres, hectares and square miles the app supports.
What are different units of area measurement on Mapulator? Nautical miles are typically used for measuring distances at sea. Kilometers and miles are often used for measuring longer distances, such as the distance between two cities. Mapulator offers several different units of measurement for distances, including meters, feet, kilometers, miles and nautical miles. What are different units of distance measurement on Mapulator? Below are some common use cases for map measurement: Area and distance measurement is useful for real estate agents and surveyors. This could include hikers, bikers or other outdoor enthusiasts who need to plan a route or estimate the distance they will need to travel. It is commonly used by individuals or organisations that need to plan routes and calculate distances or estimate the size of a specific area. What are the different users of distance and area measurement?Īrea and distance measurement tool that can be used by anyone who needs to measure distances or areas on a map.

Search location using address or zip code or city.Measure using pin, circle or drawing options.What are the different features of Mapulator? Mapulator also offers several units of measurement for distances and areas, and allows users to share their measurements and collaborate with others. Mapulator specializes in measuring distances and areas on a variety of map types such as, road maps, satellite maps, and terrain maps. It uses Google Maps and Apple Maps as the underlying map provider and provides a variety of measurement tools.

The best you can do is find something of known distance near your feature and see what it measures at to estimate the error in that area.Mapulator is a free online tool that allows users to measure area and distance on a map. Then add in the user interface - how far out are you zoomed when you do your measurements? Far enough in to see those individual original pixels, if they're even available to you? Or out far enough to see the entire field, or the field and its surroundings? What display resolution is your computer running, and how accurate/precise is your hand with the cursor as you mark the boundary? What distortions are introduced by the projection(s) Google Earth uses, which may change depending on where you are looking. Proprietary format that has been developed for the specific purpose ofĪll of that is just for the accuracy of the imagery you're measuring from. Imagery sources are fused into a single global database with a Google acquires imagery from many different sources with manyĭifferent file formats, projections and spectral characteristics. Since our database is constantly being updated, weĬannot state a specific resolution for any geographic region. Meter resolution for most of the earth's surface, with a global base Our imagery varies from sub-meter resolution in major cities to 15 Used for any navigational or other purpose requiring any accuracy These are provided for entertainment only and should not be Google makes no claims as to the accuracy of the coordinates in GoogleĮarth. This is why Google has that disclaimer about accuracy: All of which may vary in their original resolution and quality of the above processes, so right off there is no single accuracy measurement. Now let's put that all into Google Earth, which is providing you a seamless interface to multiple original sources.
On top of which, you're looking at errors introduced by (re)projection. Now let's get that into GIS, which requires both orthorectification and georeferencing. If the resolution of an image is a pixel is 1m, and you are zoomed in far enough to see individual pixels (original, not resampled for display purposes), you can measure to within +/- 1m. Let's start by taking Google Earth and even GIS out of the equation and only consider how accurate a measurement on an image can be.
I think that might be because there is no single, clear answer.
