The second setting adjusts the pointer color. The first lets you change the size of the mouse pointer and insertion point (the bar that indicates where you can click in text) to large or extra large. Go to Settings > Ease of Access > Mouse to see the two options shown here.
HOW TO CREATE A RING AROUND A POINT IN MAPINFO 10 WINDOWS 10
Windows 10 offers an easier access point. but the positions are correct with respect to the background.Finding a tiny mouse pointer can be a frustrating task, especially on a super-high-resolution laptop screen, where that white pointer can hide in plain sight.įor years, Windows has offered an option to change the size and color of the mouse pointer to overcome this annoyance, but the settings are buried in a hard-to-find Mouse Properties dialog box. Also note that the circles don't LOOK like circles because we're looking at a round earth on a flat map. (Note that if your entire file is comma-delimited and you want to draw multiple circles, you must enclose the radii in quotes, or the fields won't line up.) airportīecause we haven't supplied color values, GPS Visualizer automatically colorizes the "tracks" the same way it would GPS tracks, along a spectrum from red to violet. We'll look at ranges of both 500 and 800 nautical miles we can do that by simply separating the ranges with commas in the input file. If you manually assign a color to a point, as in the data shown here, the point's range ring(s) will take on that color.įor this map, let's say we want to visualize the flying range of a couple of airplanes from various airports. By drawing a circle of appropriate size around each of the points, we can visually locate the place where the three circles intersect: it's east of the JRO station and north of TIMB, a few kilometers south of Mt. We know the locations of the three recorders, and the great circle distance from each station to the epicenter of the tremor (the distance is calculated using the time lapse between the arrival of different kinds of earthquake waves), so we should be able to triangulate its position. This example shows data from three seismographs that all recorded an earthquake. NOTE: This works with any kind of maps that GPS Visualizer can produce: Leaflet, Google Maps, Google Earth, JPEG, PNG, or SVG. If you separate a list of distances with commas (e.g., "10mi,20mi,30mi"), you can even draw multiple rings around multiple points see the second example on this page. However, if you want to draw circles around multiple points using the Calculators page, you'd have to save all of the coordinates separately and then upload them to a map form.īut there's an easier way to do it: if you go to the map input form and supply a "circle_radius" or "range_ring" field in a manually-created waypoint file (plain text or a spreadsheet see the tutorial for more info), you can simultaneously draw circles around multiple points. GPS Visualizer's Geographic Calculators page has a form that allows you to draw a circle of any radius around a specific latitude and longitude.
