Low-Code 3D Map Application with Oracle Spatial Studio and Oracle APEX

-

 

Oracle Spatial Studio is a powerful tool for building location-based applications and performing spatial data analysis. With its intuitive user interface and deep integration with Oracle's spatial features, developers and analysts can quickly create rich, interactive map applications without requiring extensive GIS expertise. This article walks through the process of building a map application using Oracle Spatial Studio.

I suggest you watch the video below about this article.


What is Oracle Spatial Studio?

Imagine having a powerful tool that helps you turn location data into beautiful maps and insights without needing to be a tech wizard or a GIS expert. That’s Oracle Spatial Studio! It’s a free, web-based tool that makes working with spatial data as simple as drag-and-drop, while still being robust enough for advanced analyses.

If you’re working with an Oracle Database that stores location data (like addresses, coordinates, or geometries), Spatial Studio is your go-to tool for visualizing and analyzing it. Whether you're a developer, analyst, or just someone curious about maps, this tool makes it easy to create meaningful visualizations.

Here are a few cool things you can do:

  • Visualize Your Data
    Upload your spatial data (like customer locations or sales regions) and see it come to life on an interactive map.
  • Analyze Patterns
    Want to know which customers live within 10 miles of your store? Or which delivery routes are the most efficient? Spatial Studio’s spatial analysis tools make it a breeze.
  • Share Insights
    Once your map is ready, you can share it with others or embed it into a website or app. It’s perfect for team projects or customer-facing applications.

Step 1: Set Up Oracle Spatial Studio

Install and Configure Oracle Spatial Studio

  1. Download Oracle Spatial Studio
    Oracle Spatial Studio is available as a free tool for Oracle Database users. Install it on-premises or use it with an Oracle Cloud Database.
  2. Connect to Your Database
    Connect Spatial Studio to an Oracle Database instance that contains spatial data. Ensure that the database includes geospatial features such as SDO_GEOMETRY data types.

Verify Data Availability

  • If your database lacks spatial data, you can load datasets (e.g., shapefiles, GeoJSON) using Spatial Studio's data loading interface.

Step 2: Prepare Spatial Data

Import and Visualize Data

  1. Upload Files
    Use the Data Management interface to import geospatial data. Supported formats include GeoJSON, Shapefiles, CSVs with geographic coordinates, and Oracle spatial tables.
  2. Preview Layers
    Spatial Studio automatically recognizes geospatial attributes (e.g., latitude and longitude or SDO_GEOMETRY) and visualizes them as layers on a map.

Enhance Data

  • Create calculated columns, such as distance between points or buffer zones, using Spatial Studio's built-in spatial functions.
  • Perform joins to enrich spatial data with attributes from other datasets.

Step 3: Create the Map Application

Design the Map Interface

  1. Create a New Map Project
    In the Spatial Studio interface, start a new project and add relevant spatial datasets as map layers. Layers might include:
    • Points (e.g., store locations)
    • Polygons (e.g., city boundaries)
    • Lines (e.g., road networks)
  2. Customize Layer Styling
    Customize colors, symbols, and labels for your map layers to improve visualization. Use conditional formatting for dynamic styling, such as color-coding based on population density.

Add Widgets and Tools

  • Enable tools like Search, Measure, and Filter for user interaction.
  • Configure widgets to display data summaries, such as charts or heatmaps, alongside the map.

Set Up Interactivity

Define map interactions, such as:

  • Click-to-view: Display detailed information when a map feature is clicked.
  • Drill-down: Allow users to navigate from aggregated data to detailed records.

Step 4: Publish the Map Application

Configure Access

  • Set access controls to determine who can view or edit the application.
  • Publish the application to make it available to users via a web URL.

Embed or Integrate

  • Embed the map in a website or application using the provided URL or iframe code.
  • Use Oracle REST APIs to integrate your Spatial Studio project into external applications.

Oracle JET and Oracle APEX are best friends   💕    While Oracle JET is commonly associated with charts in Oracle APEX, it’s capable of much more. Oracle JET offers various tools and components for building modern web applications. The Oracle JET library required by APEX is included as part of the Oracle APEX, so there’s no need for additional installation. However, only the specific Oracle JET components used by APEX are built in, and advanced use cases require separately incorporating other parts of the full Oracle JET library.  So if developers  require additional JET components not bundled with APEX they should  manually incorporate components into their APEX applications.   What is Oracle JET? Oracle JET (JavaScript Extension Toolkit) is a free, open-source toolkit for building modern, responsive, and accessible web applications. It leverages advanced JavaScript, HTML5, and CSS3 and incorporates popular libraries like jQuery, RequireJS, and K...

Vector Tiles in Oracle Spatial 23

-
Image
Vector tiles are an efficient way to deliver and render map data in web applications. Unlike raster tiles, which are pre-rendered images, vector tiles contain raw geometries and attributes, allowing for dynamic styling and interaction on the client side. 🕮  What Are Vector Tiles? Imagine a large map divided into small, manageable square sections called "tiles."  There are two primary types of tiles: Raster Tiles : Static images representing the map. Zooming in can cause pixelation, and any style changes require generating new images. Vector Tiles : Contain raw geometric data and attributes. They allow for smooth scaling without loss of quality and enable dynamic styling, such as changing colors or labels, directly in the browser. Oracle Spatial 23c introduces support for generating and serving vector tiles directly from spatial data stored in the database. Step 1: Prepare Your Spatial Data Ensure your spatial data is stored in a table with an SDO_GEOMETRY column. CREATE T...

What is SYS.ODCI (SYS.ODCINumberList or SYS.ODCIVarchar2List) and How Can Use it in APEX ?

-
Image
⍰    What is SYS.ODCI...? Oracle database provides predefined collection types, such as  SYS.ODCINUMBERLIST and SYS.ODCIVARCHAR2LIST , which simplifies operations involving lists of numbers or strings.  SYS.ODCI  designed for bulk operations   and they  are nested table types that store lists of numbers and strings,  respectively.  ⍰    Can we use  SYS.ODCI  instead of  TABLE OF  Types ? In some cases, you can use SYS.ODCI types like instead of defining your own nested table types. For example, if you need a collection of numbers or strings, you can use these system types instead of defining something like this yourself because User-defined types require explicit definitions. In contrast, SYS.ODCINUMBERLIST and similar predefined types are readily available and can be used both in PL/SQL and SQL contexts without additional definitions. But In general,  For more complex structures (like objects with multiple...
