WARNING: This app will NOT work on Android 5.0and above devices!Enter coordinates for two points to describe line, radius of thecircle and its center point to get coordinates for points ofintersection between this line and circle. If there no such pointyou will get the shortest distance between line and center of thecircle. Also you can change tolerance for calculation, which can beuseful when you get strange answers like "no points ofintersection", and at the same time distance from center point isequal to the radius. By default tolerance is set to 0.001 to avoidit, but you can change it to 0 (Zero)or any value as you wish.N.B. Always check your Setting-Out and Calculation withdifferent methods and common sense.

NOTE: Might not be working on some Android 5.0and above devices!Transformation from given (National) grid to your own (Local)grid coordinate system can be done with this program. Program workswith Decimal Units for [Easting, Northing] or [X,Y]coordinates.Unlike some other program you don't have to know distance betweenold and new grid systems. You don't have to know bearing or skewangle between old and new grid as well.All you need is to decide where do you want to place your New LocalGrid Zero [0] point (beginning of your new coordinate system), andone more point along a New North Line to describe where isdirection for your "New North" line in New Local Grid System.- Enter National Grid coordinates for "Zero" point.- Enter National Grid coordinates for point along new "North"line.- Enter National Grid coordinates for required point "X", click"Calculate" and you have new "Local" coordinates for point "X".It is good practice to keep "North" point at least as far from"Zero" point as point "X". For example, if point "X" located 50 maway from "Zero" point, distance to point "North" should be about50 m or more. You can always use "Coordinate Calculator1" or"Traverse Coordinate Calculator" to calculate coordinates for NewLocal North point at required distance.New Grid program works with Decimal Units and[Easting,Northing]/[X,Y] coordinates . Results have 4 numbers afterdecimal point.N.B.

WARNING: This app will NOT work on Android 5.0and above devices!Little program for Site Engineers, Setting-Out Engineers,Surveyors, and for anyone who want to know where is intersectionpoint between two lines and coordinates for it. When you needquickly establish where is it on plan or in 3D you don't have to goback to office and check it with CAD any more. There is better andquicker solution - use Lines Intersection 3D program on yourAndroid phone. Use it to calculate missing coordinates for GridLines in 2D, or to check if there is possible clash between pipesand ground beams/underground services, or for whatever you want -it will give you [Easting,Northing] coordinates for intersection ofthe lines, and if you entered Z values for levels at the ends oflines, it will show you levels at crossing point for each of thelines. Also, it will show you four horizontal distances from endsof lines to intersection, and slopping (3D) distances too. If bothdistances along line are positive, that means that intersection isbetween ends of line (inside), but if one of the distances shownhas negative (-) sign, that means that intersection is outside ofthat end of the line.Limitations: If Lines are too close to each other/with small(sharp) angle between them, you might get WRONG results!In the example shown on screenshots, intersection is locatedoutside (before) point A (Line 1), and outside (before) point C(Line 2).You can always come back to previous screen to check or changeentered coordinates.Program works with Decimal Units.N.B.
