Overview

Welcome to the SpatialDBKit documentation! This documentation provides a comprehensive guide for using SpatialDBKit, a powerful framework for working with spatial databases in iOS and macOS development. Whether you are a beginner or an experienced developer, this documentation will help you get started with SpatialDBKit and explore its various features.

Installation

To start using SpatialDBKit in your iOS or macOS project, follow these steps:

Step 1 – Install Dependencies

In order to use SpatialDBKit, it is necessary to have the following dependencies installed:

  • PostGIS-enabled spatial database (e.g., PostgreSQL with PostGIS extension)

  • PostgreSQL or PostGIS client library (e.g., `libpq`)

Step 2 – CocoaPods

SpatialDBKit can be easily integrated into your project using CocoaPods.

  • Add the following line to your Podfile:

pod 'SpatialDBKit'

  • Run `pod install` command in your project’s root directory.

  • Open the generated `.xcworkspace` file.

Getting Started

Once you have successfully installed SpatialDBKit, let’s get started with a basic example:

Step 1 – Import SpatialDBKit

In the source file where you want to use SpatialDBKit, import the framework:

// Swift
import SpatialDBKit

// Objective-C
@import SpatialDBKit;

Step 2 – Use SpatialDBKit

Now you are ready to use SpatialDBKit’s powerful features. Below is a simple example of creating a new spatial database connection:

// Swift
let connection = SpatialDBConnection(databaseName: "my_database", hostname: "localhost", port: 5432, username: "user", password: "password")

// Objective-C
SpatialDBConnection *connection = [[SpatialDBConnection alloc] initWithDatabaseName:@"my_database" hostname:@"localhost" port:5432 username:@"user" password:@"password"];

Features

Spatial Queries

SpatialDBKit provides a variety of functions and methods for performing spatial queries on your database. With SpatialDBKit, you can:

  • Execute spatial queries to retrieve features within a specified area of interest.

  • Perform spatial joins to combine spatial data from multiple tables.

  • Apply spatial predicates (e.g., intersects, contains) to filter spatial data.

Geometry Manipulation

SpatialDBKit allows you to manipulate geometric objects within your spatial database. With SpatialDBKit, you can:

  • Create, modify, and delete geometric objects (e.g., points, lines, polygons).

  • Perform geometric operations like buffering, simplifying, and converting between different spatial coordinate systems.

Spatial Indexing

SpatialDBKit supports spatial indexing to optimize your spatial queries. With SpatialDBKit, you can:

  • Create and manage spatial indexes on columns in your spatial database tables.

  • Utilize advanced indexing techniques like R-Tree and Quadtree for efficient spatial search.

Data Import/Export

SpatialDBKit provides easy-to-use tools for importing and exporting spatial data. With SpatialDBKit, you can:

  • Import spatial data in various formats (e.g., GeoJSON, shapefiles) into your spatial database.

  • Export spatial data from your spatial database to different formats.
