Introduction

ArcGIS Online is a powerful web-based mapping platform that allows users to create, share, and collaborate on maps. One of the key features of ArcGIS Online is the ability to use custom basemaps, which can be used to provide a unique and personalized background for your maps. In this article, we will explore the process of uploading Nearmap basemap imagery to ArcGIS Online.

What is Nearmap Imagery?

Nearmap is a leading provider of high-resolution aerial imagery, which can be used as a basemap for ArcGIS Online maps. Nearmap imagery is captured using advanced aerial photography techniques, resulting in high-quality images with excellent resolution and accuracy. The imagery is available in various formats, including JPEG and TIFF, and can be used to create detailed and accurate maps.

Uploading Nearmap Imagery to ArcGIS Online

To upload Nearmap imagery to ArcGIS Online, you will need to follow these steps:

Step 1: Prepare the Imagery

Before uploading the imagery to ArcGIS Online, you will need to prepare it by creating a georeference file. The georeference file is a text file that contains the spatial reference information for the imagery, which is used to align the imagery with the map.

To create a georeference file, you will need to use a software tool such as Nearmap's Image Manager or a third-party georeferencing tool. The georeference file should be in the JGW format, which is a text file that contains the spatial reference information for the imagery.

Step 2: Upload the Imagery and Georeference File to ArcGIS Online

Once you have prepared the imagery and georeference file, you can upload them to ArcGIS Online. To do this, follow these steps:

Log in to your ArcGIS Online account and navigate to the "Content" tab.
Click on the "Add Item" button and select "Image" from the drop-down menu.
Upload the Nearmap imagery file (JPEG or TIFF) and the georeference file (JGW).
Fill in the required metadata fields, such as the title, description, and tags.
Click on the "Save" button to upload the imagery and georeference file to ArcGIS Online.

Step 3: Create a Basemap from the Imagery

Once the imagery and georeference file have been uploaded to ArcGIS Online, you can create a basemap from the imagery. To do this, follow these steps:

Navigate to the "Content" tab and click on the "Basemaps" tab.
Click on the "Add Basemap" button and select "Image" from the drop-down menu.
Select the Nearmap imagery that you uploaded in the previous step.
Fill in the required metadata fields, such as the title, description, and tags.
Click on the "Save" button to create the basemap.

Tips and Tricks

Here are some tips and tricks to keep in mind when working with Nearmap imagery and ArcGIS Online:

Use the correct spatial reference: Make sure that the spatial reference of the imagery matches the spatial reference of the map. This will ensure that the imagery is aligned correctly with the map.
Use the correct file format: Make sure that the imagery is in the correct file format (JPEG or TIFF) and that the georeference file is in the correct format (JGW).
Use the correct metadata: Make sure that the metadata fields are filled in correctly, including the title, description, and tags.
Use the correct basemap settings: Make sure that the basemap settings are set correctly, including the scale, resolution, and transparency.

Conclusion

In conclusion, uploading Nearmap basemap imagery to ArcGIS Online is a straightforward process that requires some preparation and configuration. By following the steps outlined in this article, you can create a high-quality basemap from Nearmap imagery and use it to enhance your ArcGIS Online maps.
