Magnetic anomalies can be either positive (field stronger than normal) or negative (field weaker) depending on the susceptibility of the rock. The data are processed via standard methods to ensure the response recorded is that due only to the rocks in the ground. The results produce datasets that can be interpreted to reveal the geological structure of the sub-surface. The processed data is checked for quality by GA geophysicists to ensure that the final data released by GA are fit-for-purpose.\nThis P903tmivd1g is a first vertical derivative of the Total Magnetic Intensity grid for the SMMSP - AEM - Honeysuckle Creek, Vic, 2001.\nThis grid has a cell size of 0.00042 degrees (approximately 42m). The grid has units of nanoTesla per km (or nT/km). The data used to produce the TMI grid was acquired in 2001 by the VIC Government, and consisted of 6082 line-kilometres of data at 200m line spacing and 115m terrain clearance. A Fast Fourier Transform (FFT) process was applied to the original grid to calculate the first vertical derivative grid.", "num_resources": 6, "num_tags": 19, "organization": {"id": "91f054ec-d0c3-4d42-a89a-5daa2c7a6818", "name": "geoscience-australia-data", "title": "Geoscience Australia Data", "type": "organization", "description": "Harvester for Geoscience Australia Data", "image_url": "", "created": "2025-06-23T12:29:08.024111", "is_organization": true, "approval_status": "approved", "state": "active"}, "original_harvest_source": {"site_url": "https://ecat.ga.gov.au", "href": "https://ecat.ga.gov.au/geonetwork/srv/eng/csw/dataset/p903tmivd1g", "title": "Geoscience Australia"}, "owner_org": "91f054ec-d0c3-4d42-a89a-5daa2c7a6818", "private": false, "promotion_level": "0", "spatial": "{\"type\": \"Polygon\", \"coordinates\": [[[145.3758, -36.7506], [145.8905, -36.7506], [145.8905, -36.4143], [145.3758, -36.4143], [145.3758, -36.7506]]]}", "spatial_coverage": "{\"type\": \"Polygon\", \"coordinates\": [[[145.3758, -36.7506], [145.8905, -36.7506], [145.8905, -36.4143], [145.3758, -36.4143], [145.3758, -36.7506]]]}", "state": "active", "temporal_coverage_from": "2001-05-04 00:00:00", "temporal_coverage_to": "2001-06-18 00:00:00", "title": "P903tmivd1g", "type": "dataset", "unpublished": false, "url": null, "version": null, "extras": [{"key": "harvest_object_id", "value": "da668b8c-d1fd-40c9-9bc1-d81257172088"}, {"key": "harvest_source_id", "value": "00080910-39e7-408f-882c-e6e1eb6baadb"}, {"key": "harvest_source_title", "value": "Geoscience Australia"}], "resources": [{"cache_last_updated": null, "cache_url": null, "created": "2025-10-17T00:12:54.189086", "datastore_active": false, "datastore_contains_all_records_of_source_file": false, "description": "The Geophysical Archive Data Delivery System (GADDS2) portal provides HTTP download of geophysics datasets in a number of formats.
