Check out these fresh new features just released on the latest version of your favorite remote sensing exploration platform, Marigold.
Marigold just keeps betting better! In our latest release we focused on features that our clients have been asking for, along with some they just haven't asked for yet. These include new ways to share results between coworkers, improved visual tools, new navigation aids, and most excitingly, our first step into temporal imagery controls that allow you to bring your data into the fourth dimension. Additionally you will find improved stability for GEOTIFF exporting and efficiency improvements across the board. Continue reading below to learn the details about everything new that Marigold has to offer.
Individual Product Export
Did you make the perfect masked product for your tricky AOI? Have you discovered a brilliant band formula that gives your company an exploration edge? Now there is no need to share .sav files for multiple users to access your proprietary products. In Marigold 2.2.0, you will find the new option to
Export any of your Raster Layers under the three dot menu next to each layer. In the export dialogue you have options to specify your layer's name, add a brief description, and select who will have access. By default, the layer will only be available to you. You may optionally share the layer to a list of individuals by email address or make it available to all Marigold users in your organization.
To import a layer, click the plus icon next to
Raster Layers on the left hand menu. In addition to the
Catalog layer option you are familiar with, you will now find
Load exported layer that will bring you to a list of available layers that you have made or have been shared with you. Select a product, click
Load layer, and voila! You can also download the layer through this interface as a .lyr file and share the file directly to another Marigold user. Imported layers will have all of the same masking, bands, and settings as the original exported layer.
To export and share your favorite Marigold product, select Export from the layer's three-dot menu, provide a name, description, and adjust the settings to control who can access the layer. Marigold collaboration just got easier.
Mask Above or Below Threshold Values
Are you interested in the most intense areas of an alteration signature? Two new checkboxes have been added to help you better visualize and contextualize your mapping products. These are the
Mask low values and
Mask high values options located above the histogram plot in the settings panel of each raster layer. Simply toggle the boxes to instantly mask values above and below your thresholds to reveal the imagery underneath. This quick visual setting has been highly requested by our users and we are excited to bring the capability into the software.
Note: GEOTIFF output of layers with these settings applied will not contain the masking as this feature is purely for visualization in Marigold and does not remove the underlying data from the layer in the same way as the
Apply mask tool.
Use the new tools in each layer's settings menu to mask values above or below a threshold value. Simply click the checkbox to instantly remove pixels below your chosen value and visualize the results in better spatial context.
Zoom to AOI
Looking for a needle in a haystack? Sometimes locating a small airborne imagery dataset can be harder than it sounds, even if you know the general location! A new tool has been added to the three-dot menu of raster layers that allows users to
Zoom to AOI for any spatially restricted dataset in your workspace.
While most rocks don't move on their own, humans and nature have a way of changing our planet over time which means that applications of remote sensing, even in exploration, are not always a static affair. In Marigold 2.2.0, you will now find basic temporal controls in the settings menu of certain products that contain acquisition date information. That means you can explore Airbus SPOT imagery to find time-relevant scenes over your AOI, or unstack overlapping EnMap scenes to visualize only your preferred image. Maybe there was a cloud in the Airbus imagery you have been using? Give this tool a try to find a better scene for your project.
This is the first step into a new frontier for Marigold and we are exciting for the possibilities it may hold. What applications do you foresee adding to your remote sensing exploration workflow? Assessing historical vegetation change? Tracking glacial retreat? Monitoring tailings through annual airborne surveys? Get in touch and let us know! We look forward to building out powerful temporal tools in Marigold to empower you to analyze the data for your projects with ease.
Layers with temporal data can now be manipulated within the settings menu of those layers. Select the start and end collection dates within the settings panel and the imagery will be filtered based on your inputted range.
Note that changing the time range on Airbus SPOT imagery will temporarily produce a white image due to color scaling from 0-1 instead of 0-255. Simply contrast stretch the image with the magic wand tool to visualize your imagery.
