geoengine 0.0.3

GeoEngine is a potent Dart library for geospatial analysis and geomatic. It has precise distance calculations, coordinates conversions, geodetic processing, and GIS support in Dart.

GeoEngine

GeoEngine is a comprehensive Dart library designed for geospatial and geomatic calculations. It provides a wide range of functionalities including distance calculations, coordinate conversions, geocoding, polygon operations, geodetic network analysis, and much more. Whether you are a GIS professional, a geomatics engineer, or a developer working on geospatial applications, GeoEngine is the ultimate toolkit for all your geospatial needs.

Features

Core Calculations

• Distance Calculation: Calculate the distance between two geographic coordinates using various algorithms like Haversine, Vincenty, and Great Circle.
• Bearing Calculation: Calculate the initial and final bearing between two points on the Earth's surface.
• Geodesic Calculations: Find the shortest path between two points on the Earth's surface, taking into account the Earth's curvature.

Coordinate Systems

• Coordinate Conversion: Convert between different coordinate systems, such as latitude/longitude to UTM or MGRS.
• Datum Transformations: Transform coordinates between different geodetic datums.

Geocoding

• Geocoding and Reverse Geocoding: Convert addresses into geographic coordinates and vice versa.

Polygon Operations

• Polygon Operations: Create, manipulate, and analyze polygons, including point-in-polygon checks, area calculations, and finding centroids.

Map Projections

• Map Projections: Support for various map projections and functions to transform coordinates between different projections.

Spatial Indexing

• Spatial Indexing: Utilize spatial indexing techniques like R-trees or Quad-trees for efficient querying of spatial data.

Geomatic Calculations

• Error Propagation: Estimate the uncertainty in spatial measurements.
• Least Squares Adjustment: Perform least squares adjustment for surveying measurements.
• Traverse Calculations: Perform closed and open traverse calculations.
• Geodetic Networks: Design and analyze geodetic networks.
• Land Parcel Management: Manage land parcels including subdivision and legal description generation.

Remote Sensing

• Remote Sensing Calculations: Perform calculations such as NDVI, radiometric correction, and image classification.

Digital Elevation Models

• DEM Analysis: Work with Digital Elevation Models, including slope, aspect, and watershed analysis.

Route Planning

• Route Planning: Algorithms for route planning and optimization.

GIS File Support

• GIS File Support: Read and write common GIS file formats like Shapefiles, GeoJSON, and KML.

Integration with Mapping Services

• Integration with Mapping Services: Integrate with popular mapping services like Google Maps, OpenStreetMap, and Bing Maps.

Getting Started

Installation

Add this to your package's pubspec.yaml file:

dependencies:
  geoengine: any

Usage

Here's a simple example to calculate the distance between two geographic coordinates:

import 'package:geoengine/geoengine.dart';

void main() {
  var point1 = LatLng(37.7749, -122.4194);
  var point2 = LatLng(34.0522, -118.2437);

  var distance = GeoEngine.calculateDistance(point1, point2);

  print('Distance between points is: ${distance} meters');
}
